Umhlaba wezinto zikagesi zanamuhla wakhelwe phezu kwesisekelo sezinto ezikhethiweyo ezenziwe ngobuciko ezingakwazi ukulawula ukugeleza kukagesi ngokunemba okumangalisayo. Enhliziyweni yalolu hlelo lobuchwepheshe kukhona umqondo we-semiconductor, into yokwakha ukuqhuba kwayo kukagesi kuphakathi kwe-conductor ne-insulator. Ochwepheshe abaningi abasebenza ekwenzeni noma ekuthengeni izinto zikagesi, incazelo ye-semi conductor idlula kude nencazelo elula yencwadi; imelela umgogodla wokusebenza cishe kwayo yonke into kagesi esetshenziswa namuhla. Ukuqonda izinhlobo ezahlukene zezinto ze-semiconductor kubalulekile ukuze kuthathwe izinqumo ezinolwazi mayelana nezingxenye, kusukela kuma-diode alula kuya kuma-integrated circuit ayinkimbinkimbi. Lesi sihloko sinikeza ukuhlola okuphelele kwezinhlobo ze-semiconductor, siqala ngezigaba eziyisisekelo ze-n-type ne-p-type, sidlule ezintweni zendabuko, sigcine ngokuhlola izixazululo eziphambili ze-p-type ezichaza kabusha okungenzeka ku-electronics emincane kanye ne-optoelectronics. Ekupheleni kwale ngxoxo, ochwepheshe bebhizinisi kanye nabathatha izinqumo zobuchwepheshe bayoba nokuqonda okucacile kokuthi ukukhethwa kwezinto kuthinta kanjani ukusebenza, ukuthembeka, kanye nokusebenza isikhathi eside kwemikhiqizo yabo.

Ukuze siqonde ukubaluleka kwentuthuko yakamuva kubuchwepheshe be-p-type semiconductor, kudingeka kuqala sibe nokuqonda okuqinile ngezinhlobo eziyisisekelo zokuhlukaniswa kwama-semiconductor alawula ukusebenza kwama-device. Ama-semiconductor ahlukaniswa ngokubanzi abe yizinhlobo ezingaphakathi (intrinsic) nezangaphandle (extrinsic), kanti lezi zokugcina zihlukaniswa zibe yizinto ezinhlobo ze-n-type ne-p-type ngokusekelwe kumthwali oyinhloko wamandla kagesi. Ku-n-type semiconductor, into ifakwa izithako ezinikelayo (donor impurities) eziletha ama-electron engeziwe, okwenza ama-electron abe yizithwali eziningi. Ngokuphambene, i-p-type semiconductor yakhiwa ngokufaka izithako ezamukelayo (acceptor impurities) ezidala inqwaba yezikhala ezinomthwalo omuhle (holes), ezibe yizithwali eziyinhloko zokuhamba kwamandla kagesi. Lo mehluko phakathi kwezinto ezinama-electron amaningi nezinezikhala eziningi uyisisekelo lapho kwakhiwa khona cishe wonke ama-device e-semiconductor, kusukela ku-diode elula yokulungisa amandla kagesi kuya ku-microprocessor oyinkimbinkimbi kakhulu. Ukusebenzisana phakathi kwezindawo ze-n-type ne-p-type ngaphakathi kwedivayisi kunika amandla ukushintsha okulawulwayo, ukukhulisa amandla, nokucubungula amasignali okuyikhona okuchaza ubuchwepheshe banamuhla. Isibonelo, i-bipolar junction transistor ye-npn incike ekuhlelweni okunembile kwezingqimba ze-n-type ne-p-type ukuze kutholakale ukukhulisa amandla kagesi, okubonisa ukuthi lezi zinhlobo eziyisisekelo zezinto zisebenza kanjani ndawonye ekusetshenzisweni okungokoqobo. Ubuchwepheshe be-complementary metal oxide semiconductor (CMOS), obubusa umkhakha we-integrated circuit, busebenzisa amapheya ahambisanayo e-MOSFETs ezinhlobo ze-n-type ne-p-type ukuze kutholakale ukusetshenziswa kwamandla okuphansi kakhulu nokungazweli emsindweni ophakeme. Ngaphandle kwento eqinile nethembekile ye-p-type, uhlelo lonke lwe-CMOS lungabhekana nemikhawulo emibi kakhulu ekusebenzeni. Ngakho-ke, ukuqonda izici kanye nemikhawulo yohlobo ngalunye lwe-semiconductor akuwona nje umsebenzi wezemfundo; kuyisici esibalulekile ekukhetheni izingxenye ezifanele zanoma yiluphi uhlelo lwe-elekthronikhi.

Ukubaluleka kwe-p-type semiconductors kunweba cishe kuyo yonke imikhakha yemboni yezobuchwepheshe, okuhlanganisa izinto zikagesi zabathengi, amasistimu ezimoto, ezokuxhumana, namandla avuselelekayo. Emishinini ye-optoelectronic efana nama-LED (ama-diode akhanyayo) nama-laser diode, ukufakwa kahle kwama-hole (izikhala) kusuka kungqimba lwe-p-type kuya endaweni esebenzayo kubalulekile ukuze kutholakale ukukhanya okuphezulu nokukhanya okugqamile. Ngokufanayo, kumaseli e-photovoltaic, ungqimba lwe-p-type ludlala indima ebalulekile ekudaleni insimu kagesi eyakhelwe ngaphakathi ehlukanisa izithwali zikagesi ezikhiqizwa ukukhanya, okuthinta ngqo ukusebenza kahle kokuguqulwa kweseli. Kubakhiqizi nochwepheshe bokuthenga, ukutholakala nokusebenza kwezinto ze-p-type kungathonya konke kusukela ezikhathini zokuklanywa komkhiqizo kuya ekuthembekeni kochungechunge lokuhlinzeka. Njengoba ubukhulu bemishini buqhubeka buncipha futhi izidingo zokusebenza zikhula, imikhawulo yezinto ezijwayelekile ze-p-type iba sobala kakhulu, okushukumisela isidingo sezinye izindlela ezithuthukisiwe ezinganikeza ukuhamba kwama-hole okuphezulu, ukuzinza okungcono, nokuguquguquka okukhulu ekucubungulweni. Lokhu kuguquka okuqhubekayo ezinhlotsheni zezinto ze-semiconductor kuthinta ngqo amandla ezinto zikagesi zesizukulwane esilandelayo, okwenza kube semqoka ukuthi ababambiqhaza bemboni bahlale benolwazi ngentuthuko yakamuva kusayensi yezinto ze-p-type.

IsiSilicon ne-germanium zibe yizinsika zomkhakha we-semiconductor amashumi eminyaka, futhi izici zazo zaziwa kahle onjiniyela nezazi zezinto zomhlaba wonke. I-Silicon, ikakhulukazi, iyona ehamba phambili emakethe ngenxa yobuningi bayo, ingqalasizinda yokucubungula evuthiwe, kanye ne-oxide yemvelo esezingeni eliphezulu eyenza izinto ezinama-insulated-gate zisebenze. Nokho, uma kukhulunywa nge-p-type doping, kokubili i-silicon ne-germanium zikhombisa ukulinganiselwa okukhulu okuvimbela ukusebenza kwemishini. Ukuhamba kwezimbobo (hole mobility) ku-silicon kuphansi kakhulu kunokuhamba kwama-electron, okudala ukungalingani okungokwemvelo phakathi kwama-transistor e-n-type ne-p-type kumasekhethi e-CMOS. Lokhu kungalingani kuphoqa abaklami ukuthi basebenzise ama-transistor amakhulu e-p-type ukuze bathole isivinini sokushintsha esilinganayo, okwandisa indawo nokusetshenziswa kwamandla kwamasekhethi ahlanganisiwe. I-Germanium inikeza ukuhamba kwezimbobo okuphezulu kune-silicon, okuyenza ihehe izicelo ze-p-type, kodwa ihlushwa ukuntuleka kwe-oxide yemvelo ezinzile kanye nokuzwela okukhulu ekushintsheni kwezinga lokushisa, okwenza kube nzima ukuyihlanganisa ezinqubweni ezijwayelekile zokukhiqiza. Lezi zingqinamba ziye zagqugquzela ucwaningo olunzulu lwezinto ezinye ezinganikeza ukusebenza okungcono kwe-p-type ngaphandle kokulahlekelwa ukukhiqizeka nokwethembeka okudingwa umkhakha.

Ngaphezu kwezinto eziyisisekelo ze-semiconductor ezifana ne-silicon ne-germanium, ama-compound semiconductors avela emaqenjini III-V (anjenge-gallium arsenide, indium phosphide) kanye namaqembu II-VI (anjenge-zinc oxide, cadmium telluride) anikeza izakhiwo ezikhethekile ze-optoelectronic ezingcono kune-silicon ezintweni eziningi. Isibonelo, i-gallium arsenide ine-bandgap eqondile evumela ukukhishwa kokukhanya okuphumelelayo, okwenza kube into ebalulekile kuma-laser diode kanye nama-solar cell asebenza kahle kakhulu. Nokho, lezi zinto ezihlanganisiwe nazo zibhekana nezinselelo uma zisetshenziswa njengezendlalelo zohlobo lwe-p. Izinto eziningi ze-III-V zinokusebenza kabi kwe-doping yohlobo lwe-p ngenxa yokwakheka kwamaphutha okunxephezela noma ukuncipha kokuncibilika kwe-acceptor impurities. Kwezinye izimo, amazinga aphezulu angatholakala e-hole awanele ukwenza ama-ohmic contacts anokumelana okuphansi, okulimaza ukusebenza kwedivayisi futhi kwandise ukulahleka kwamandla. Ngaphezu kwalokho, izindleko eziphakeme zama-substrates kanye nobunkimbinkimbi bezinqubo zokukhula kwe-epitaxial kuma-compound semiconductors amaningi kukhawulela ukusetshenziswa kwazo ezintweni ezikhethekile lapho izakhiwo zazo eziyingqayizivele zithethelela izindleko. Emabhizinisini afuna uhlobo lwe-semiconductor olulinganisa ukusebenza, izindleko, nokukhula, lezi zinto ezivamile zivame ukudinga ukuhweba ngokucophelela okungenzeka kungamukeleki ezintweni ezintsha ezifana ne-flexible electronics, izinzwa ezinkulu, noma izinto ezigqokwayo. Ukufunwa kwento yohlobo lwe-p ehlanganisa i-hole mobility ephezulu, i-bandgap tunability ebanzi, kanye nokucutshungulwa kwamazinga okushisa aphansi kuye kwaba umgomo omkhulu wocwaningo lwezinto zanamuhla.

Esinye sezithiyo eziyisisekelo kusayensi yezinto ezibonakalayo ze-semiconductor ubunzima obungokwemvelo bokuthola ukusebenza okuphezulu kwe-p-type conduction ezinhlelweni eziningi zezinto. Umsuka wale nselele usesakhiweni se-elekthronikhi sezinto eziningi ze-semiconductor, lapho i-valence band isuselwa kuma-atomic orbitals ahlukaniswe kakhulu kunama-conduction band orbitals. Lokhu kuhlukaniswa kubangela ukuthi ama-hole abe nezisindo eziphezulu uma kuqhathaniswa nama-electron, okuholela ekutheni ama-hole abe nokuhamba okuphansi. Ngamazwi asebenzayo, lokhu kusho ukuthi ngisho noma into ingafakwa i-p-type, ukuhamba kwama-hole okuvelayo kuvame ukuba ngokuphindwe kashumi kuphansi kunokuhamba kwama-electron entweni efanayo. Lokhu kungafani kudala isithiyo ekusebenzeni kwemishini ethembele ekuhambeni okulinganiselayo kwama-charge carrier womabili. Isibonelo, ku-complementary metal oxide semiconductor inverter, isivinini sokushintsha sikhawulelwa yi-p-type transistor enensayo, okunciphisa imvamisa yomjikelezo wonke. Ukunqoba lo mkhawulo kudinga ukuthola izinto ezinokuhamba okuphezulu kwama-hole ngokwemvelo noma ukuthuthukisa izindlela ezintsha zokufaka i-doping ezingathuthukisa ukusebenza kwe-p-type ngaphandle kokwethula amaphutha anxephezela noma ukungazinzi kwesakhiwo.

Omunye inselelo enkulu ukuthi kuncane izinhlelo zezinto ezibonisa ukufakwa kwe-p-type okuthembekile nokungaphindaphindeki. Ama-oxide amaningi ane-bandgap ebanzi, aheha kwezobuchwepheshe obusobala namadivayisi amandla aphezulu, anomkhuba oqinile wokwakha ukuqhuba kwe-n-type ngenxa yeziphambeko zomnikeli womdabu njengezikhala zomoya-mpilo. Kulezi zinto, ukuthola ukufakwa kwe-p-type kunzima kakhulu ngoba iziphambeko ezifanayo ezidala ukuqhuba kwe-n-type ziphinde zinxephezele izithako ezamukelayo, zibambe i-Fermi level eduze kwe-conduction band. Ngaphezu kwalokho, izithako eziningi ze-p-type zinokuncibilika okuphansi ku-lattice yomkhaya, futhi lezo ezihlanganisayo zingasakazeka ngokushesha ngesikhathi sokusebenza kwedivayisi, okuholela ekungazinzini nasekwehleni kokusebenza ngokuhamba kwesikhathi. Ukushoda kwezinto eziqinile ze-p-type kuwumkhawulo owaziwayo oye wabambezela ukuthuthukiswa kwe-electronics esekwe ku-oxide, ama-bipolar transistors, neminye imishini ye-optoelectronic. Ezinkampanini ezihilelekile ekuthengeni izingxenye ze-semiconductor ze-p-type, lezi zinselelo ezisezingeni lezinto ziholela ezindlekweni eziphakeme, emjikelezweni omude wokuthuthukisa, nasezinkethweni ezilinganiselwe zomthengisi. Umkhakha udinga ngokushesha izinto ezithuthukile ze-p-type ezingakwazi ukuletha ukusebenza okungaguquki, okuphezulu ngaphansi kwezimo zomhlaba wangempela, okuhlanganisa ukuchayeka emazingeni okushisa aphakeme, umswakamo, nengcindezi yemishini. Ukubhekana naleli dinga kudinga izindlela ezintsha zokwakha izinto ezingaphezu kwezindlela zokufaka ezijwayelekile.

Ngokuphendula izinselelo ezinde ezikhona ngezinto ezijwayelekile zohlobo lwe-p, abacwaningi bathuthukise i-alloy eyinkimbinkimbi ye-inorganic eyaziwa ngokuthi i-TeSeO, emele isinyathelo esibalulekile ekufuneni ukusebenza okuphezulu kwe-p-type conduction. I-TeSeO iyi-alloy ye-ternary chalcogenide ehlanganisa i-tellurium, i-selenium, ne-oxygen nge-stoichiometry elungiselelwe ngokucophelela ukuze kutholakale izakhiwo ezihlukile zikagesi. Le nto yakhiwa kusetshenziswa inqubo yokufaka i-deposition ezingeni lokushisa legumbi, okwenza ihambisane nezinhlobonhlobo zama-substrates, okuhlanganisa ama-polymers aguquguqukayo namaphaneli amakhulu engilazi. Leli khono lokucubungula izinga lokushisa eliphansi liyinguquko ezintweni lapho izindlela zokukhiqiza ezijwayelekile ezinokushisa okuphezulu zingalimaza i-substrate noma zengeze izindleko ezingenakubaluleka. Ngokombono webhizinisi, ikhono lokufaka i-semiconductor yohlobo lwe-p esezingeni eliphezulu ezingeni lokushisa legumbi livula amathuba amasha okukhiqiza ama-thin-film transistors, ama-photodetectors, nama-sensor arrays ezinkundleni eziguquguqukayo nezingasindi, okuhlangabezana nesidingo esikhulayo semakethe se-wearable electronics namadivayisi e-Internet of Things (IoT).

Ukusebenza kukagesi kwe-TeSeO kuhle kakhulu uma kuqhathaniswa nezinto ezikhona zohlobo lwe-p. Le nto ibonisa i-bandgap elungisekayo esukela ku-0.7 electron volts kuya ku-2.2 electron volts, okuvumela onjiniyela ukuthi bathuthukise ukumuncwa kokukhanya kanye nokuqhuba kukagesi kwale nto ngezinhlelo ezithile. Isibonelo, i-bandgap encane ifiseleka ekutholeni imisebe ye-infrared, kuyilapho i-bandgap enkulu ifaneleka kangcono kwezinto zikagesi ezibonakalayo noma ekusebenzeni emazingeni okushisa aphezulu. Ukuhamba kwezimbobo (hole mobility) ku-TeSeO kulinganiswe kwaze kwafika ku-48.5 square centimeters per volt-second, okuphakeme kakhulu kuma-semiconductor asuselwa ku-oxide ohlobo lwe-p futhi kuqhudelana noma kudlula ukuhamba kwezimbobo kwamanye ama-III-V compounds. Lokhu kuhamba okuphezulu kuhumushela ngqo ekushintsheni okusheshayo kanye namandla aphezulu okuqhuba kuma-thin-film transistors, okunika ukusebenza okungcono kuma-display backplanes, ama-logic circuits, kanye nama-RF identification tags. Ukwengeza, amafilimu e-TeSeO abonisa ukuqina okumangalisayo ngokomshini, emelana nemijikelezo ephindaphindiwe yokugoba ngaphandle kokwehla okukhulu ezintweni zikagesi. Kochwepheshe bokuthenga abahlola izinhlobo ezahlukene zezinto ze-semiconductor, i-TeSeO inikeza inhlanganisela ephoqelelayo yokusebenza okuphezulu, ukuguquguquka ekucubungulweni, kanye nokuqina ngokomshini okunzima ukukuthola kwezinye izinketho zohlobo lwe-p. Le nto iyisibonelo sohlobo lokuqamba okungaxazulula i-p-type bottleneck futhi kunike amandla izizukulwane ezilandelayo zezinto zikagesi.

Izici eziyingqayizivele ze-TeSeO ziyenza ibe yisisekelo esifaneleka kakhulu ekusetshenzisweni okuhlukahlukene okungokoqobo, ikakhulukazi emikhakheni ye-electronics yamafilimu amancane kanye ne-optoelectronics. Enye yezindawo zokusebenza ezithembisayo kakhulu kuma-thin-film transistors (TFTs) ezobuchwepheshe bokubonisa, lapho ukuhamba kwama-hole okuphezulu kwe-TeSeO kunika amandla ukushintsha kwama-pixel okusheshayo kanye namazinga okuvuselela aphakeme uma kuqhathaniswa ne-amorphous silicon evamile noma ama-organic TFTs. Lokhu kusebenza okuthuthukisiwe kubaluleke kakhulu kuma-displays anesisindo esiphezulu asetshenziswa kuma-virtual reality headsets, izibuko ze-augmented reality, kanye nemishini ethuthukile yokuthwebula izithombe kwezokwelapha. Inqubo yokufaka i-room-temperature iphinde ivumele ama-TeSeO TFTs ukuthi akhiqizwe kuma-flexible plastic substrates, okuvumela ukuthuthukiswa kwama-displays agobekayo nagoqekayo athandwa kakhulu kuma-consumer electronics. Ezinkampanini ezihilelekile ku-display supply chain, ukutholakala kwe-p-type material eqinile efana ne-TeSeO kungenza ukuklanywa kwesekethe kube lula, kunciphise ukusetshenziswa kwamandla, futhi kuthuthukise ukwethembeka komkhiqizo jikelele. Ukusetshenziswa kwe-TeSeO kuma-bipolar junction transistor npn configurations nakho kuyenzeka uma kuhlanganiswa ne-n-type layers ezifanele, kunikeza izindlela ezintsha zokukhulisa i-high-gain amplification kumafomethi amafilimu amancane.

Enye indawo ebalulekile yokusetshenziswa kwe-TeSeO kuma-photodetector kanye nezinzwa zokuthwebula izithombe. I-bandgap elungisekayo yale nto ivumela ukuthi ilungiswe ukuze ikwazi ukuzwela ebangeni elibanzi le-spectral, kusukela emisebeni ye-ultraviolet kuya kuma-wavelengths aseduze ne-infrared. Lokhu kuguquguquka kwenza ama-photodetector asuselwa ku-TeSeO afanelekele ukusetshenziswa ekuqapheni imvelo, ekuhloleni izimboni, ekuthwebuleni izithombe ze-biomedical, kanye nezinhlelo zokuphepha. Ukuhamba okuphezulu kwe-hole kuqinisekisa ukuthi ama-carrier akhiqizwa ukukhanya aqoqwa ngokushesha, okuholela ezikhathini zokuphendula ezisheshayo kanye nokutholwa okuphezulu. Ngaphezu kwalokho, ukuqina kwemishini yama-TeSeO films kusho ukuthi ama-photodetector angahlanganiswa nezinzwa ezigqokwayo okufanele zibekezelele ukunyakaza nokuthintana okuphindaphindiwe. Kubaphathi bokuthenga abahlola izinhlobo zezinketho ze-semiconductor zezicelo zezinzwa, i-TeSeO inikeza inhlanganisela eyivelakancane yokuzwela okuphezulu, ukuphendula okusheshayo, nokuguquguquka kwemishini okungahlukanisa imikhiqizo yabo emakethe enokuncintisana. Le nto iphinde ibonise ukuzinza okuhle kwesikhathi eside ngaphansi kwezimo ezijwayelekile, kunciphisa isidingo sokufakwa kwe-encapsulation eyinkimbinkimbi futhi kwehlise izindleko zokukhiqiza jikelele. Njengoba isidingo sezixazululo eziphambili zokuzwa siqhubeka sikhula kuzo zonke izimboni, izinto ezifana ne-TeSeO ezingaletha ukusebenza okuphezulu ngaphandle kokulahla ukukhiqizeka ziyoba zibaluleke kakhulu.
