Ama-semiconductor akha umgogodla wezinto zikagesi zanamuhla, enika amandla konke kusukela kumakhalekhukhwini kuya emishinini yezimboni. Lezi zinto, ngokuvamile ezenziwe nge-silicon, zinokuqhutshwa kukagesi okuphakathi kwezinto eziqhutshwayo nezingaqhutshwa, okwenza zilungele ukugeleza kukagesi okulawulwayo. Izici eziyingqayizivele ze-p type semiconductor, ezakhiwa ngokufakwa kwama-athomu ama-acceptor, zivumela ukwakheka kwama-p-n junctions ayisisekelo emishinini kagesi. Ukuqonda izinhlobo ezahlukene zama-semiconductor kubalulekile konkunkuli nezisebenzi ezithengayo ezidinga ukukhetha izingxenye ezifanele zezicelo zazo. Ngaphandle kolwazi oluqinile ngezinhlobo zama-semiconductor, izinkampani zingase zikhethe izingxenye ezingasebenzi kahle noma ezingahambisani ezithikameza ukusebenza komkhiqizo. Umkhakha wama-semiconductor emhlabeni wonke uyaqhubeka ukhula ngokushesha, uqhutshwa yisidingo sezinto zikagesi ezihlakaniphile, ezisheshayo, nezonga amandla. Ezinkampanini ezifuna ukuhlala ziqhudelana, ukwazi izigaba ezibalulekile zama-semiconductor namandla azo kuyisinyathelo sokuqala esibalulekile.

Inhliziyo yazo zonke izinto zikagesi inenhlanganisela enakekelwe kahle yezingxenye ze-semiconductor ezisebenza ndawonye ngokungenasici. Kusukela ku-diode elula yokulungisa amandla kuya ku-microprocessor eyinkimbinkimbi kakhulu, ingxenye ngayinye yakhelwe izimiso ezithile zomzimba. Amandla okulawula ukugeleza kwama-electron ezintweni ezinjenge-silicon aguqule ubuchwepheshe bekhompyutha, ukuxhumana, nokuphathwa kwamandla. Izimboni zanamuhla zithembele kakhulu kubuchwepheshe obuthuthukile be-semiconductor ukuze zithole ukusebenza kahle nokunciphisa ubukhulu emikhiqizweni yazo. Lo mhlahlandlela uhlola izinhlobo ezibalulekile ze-semiconductor ezikhona namuhla futhi uchaza ukuthi ingxenye ngayinye isebenza kanjani emisebenzini ehlukene ezinhlelweni zikagesi. Ekugcineni, abafundi bayoba nokuqonda okucacile kokuthi bangafanisa kanjani izinhlobo ze-semiconductor nezidingo zabo eziqondile zephrojekthi kanye namasu okuthenga.

Ama-diode aphakathi kwezinto ezilula kodwa ezibaluleke kakhulu kwezokwakha izinto zikagesi eziyi-semiconductor, ahlanganisa i-p-n junction evumela ukuthi ugesi ugeleze ngendlela eyodwa kuphela. Asetshenziswa kakhulu ekulungiseni ugesi emithonjeni yamandla, eguqula ugesi oshintshashintshayo ube ugesi oqondile ngokusebenza kahle kakhulu. Izinhlobo ezivamile zihlanganisa ama-rectifier diode, ama-Zener diode okulawula amandla kagesi, ama-Schottky diode okushintsha ngokushesha, nama-light-emitting diode okukhanyisa. Uhlobo ngalunye lwe-diode lusebenzisa izici eziyisisekelo ze-semiconductor yohlobo lwe-p kanye ne-semiconductor yohlobo lwe-n ezihlanganisiwe ukuze kwakheke indawo yokuncipha. Ukuziphatha kwale junction kunquma ukwehla kwamandla kagesi phambili kwe-diode, amandla ayo okugqashuka, kanye nesivinini sayo sokushintsha. Onjiniyela bakhetha izinhlobo ezithile zama-diode ngokusekelwe emingceleni efana ne-current rating, i-reverse recovery time, kanye nokuzinza ekushintsheni kokushisa.
