Thepa ea semiconductor ea silicon carbide

Carbide ea silicon (SiC)Thepa ea semiconductor ke eona e hōlileng ka ho fetisisa har'a li-semiconductor tse nang le lekhalo le leholo la sehlopha se seholo tse ntlafalitsoeng. Thepa ea semiconductor ea SiC e na le bokhoni bo boholo ba ts'ebeliso mochesong o phahameng, maqhubu a phahameng, matla a phahameng, li-photoelectronics le lisebelisoa tse hanelang mahlaseli ka lebaka la lekhalo la tsona le leholo la sehlopha, tšimo ea motlakase e senyehang haholo, conductivity e phahameng ea mocheso, ho tsamaea ha li-electron tse ngata le boholo bo bonyenyane. Silicon carbide e na le mefuta e mengata ea ts'ebeliso: ka lebaka la lekhalo la eona le leholo la sehlopha, e ka sebelisoa ho etsa li-diode tse ntšang leseli le leputsoa kapa li-detector tsa ultraviolet tse sa angoeng ke khanya ea letsatsi; Hobane matla a motlakase kapa tšimo ea motlakase e ka mamelloa ka makhetlo a robeli ho feta silicon kapa gallium arsenide, haholo-holo e loketseng ho etsa lisebelisoa tse nang le matla a phahameng a motlakase tse kang li-diode tse nang le motlakase o phahameng, li-triode tsa motlakase, lisebelisoa tsa microwave tse laoloang ke silicon le tse nang le matla a phahameng; Ka lebaka la lebelo le phahameng la ho falla ha li-electron tse ngata, e ka etsoa hore e be mefuta e fapaneng ea lisebelisoa tse nang le maqhubu a phahameng (RF le microwave);Carbide ea siliconke mokhanni o motle oa mocheso 'me o tsamaisa mocheso hamolemo ho feta thepa efe kapa efe ea semiconductor, e leng se etsang hore lisebelisoa tsa silicon carbide li sebetse maemong a phahameng a mocheso.

Mohlala o ikgethang, APEI hajwale e ntse e itokisetsa ho ntshetsa pele sistimi ya yona ya DC motor drive ya tikoloho e feteletseng bakeng sa Venus Explorer (VISE) ya NASA e sebedisa dikarolo tsa silicon carbide. E ntse e le mohatong wa moralo, sepheo ke ho lahlela diroboto tsa ho hlahloba hodima Venus.

Ho phaella moo, skhabide ea siliconE na le tlamo e matla ea ionic covalent, e na le bothata bo phahameng, ho tsamaisa mocheso ho feta koporo, ts'ebetso e ntle ea ho qhala mocheso, khanyetso ea mafome e matla haholo, khanyetso ea mahlaseli a kotsi, khanyetso ea mocheso o phahameng le botsitso bo botle ba lik'hemik'hale le thepa e meng, e na le mefuta e mengata ea lits'ebetso lefapheng la theknoloji ea lifofane. Mohlala, ts'ebeliso ea thepa ea silicon carbide ho lokisetsa lifofa-sebakeng bakeng sa bo-ralifofane, bafuputsi ho phela le ho sebetsa.
