unamathela we-sic I-Silicon carbide enamathela I-SiC embozwe nge-Graphite substrate yeSemiconductor

I-SiC inezakhiwo ezinhle kakhulu zomzimba namakhemikhali, njengendawo ephezulu yokuncibilika, ukuqina okuphezulu, ukumelana nokugqwala kanye nokumelana ne-oxidation. Ikakhulukazi ebangeni lika-1800-2000 ℃, i-SiC inokumelana okuhle nokukhipha umoya. Ngakho-ke, inamathemba okusebenza abanzi ku-aerospace, imishini yezikhali kanye neminye imikhakha. Kodwa-ke, i-SiC ngokwayo ayikwazi ukusetshenziswa njengea isakhiwoimpahla,ngakho-ke indlela yokwemboza ivame ukusetshenziswa ukuze kusetshenziswe ukumelana kwayo nokuguga kanye ne-ablation resistance.

I-silicon carbide(SIC) impahla ye-semiconductor iyisizukulwane sesithathu seimpahla ye-miconductor eyakhiwe ngemva kwento yokuqala yesizukulwane se-semiconductor material (Si, GE) kanye nesesibili isizukulwane semiconductor material (GaAs, gap, InP, njll.). Njengempahla ye-semiconductor ye-band gap ebanzi, i-silicon carbide inezici zobubanzi begebe lebhande elikhulu, amandla ensimu yokuphuka okuphezulu, ukuqhutshwa kwe-thermal conductivity, isivinini sokukhukhuleka se-carrier saturation, i-dielectric encane engaguquki, ukumelana nemisebe eqinile nokuzinza okuhle kwamakhemikhali. Ingasetshenziselwa ukukhiqiza amadivaysi ahlukahlukene aphezulu-imvamisa kanye namandla aphezulu anokumelana nokushisa okuphezulu futhi ingasetshenziswa ezikhathini lapho amadivaysi e-silicon engafaneleki khona, Noma akhiqize umphumela wokuthi amadivaysi e-silicon anzima ukukhiqiza izinhlelo zokusebenza ezijwayelekile.

Uhlelo lokusebenza oluyinhloko: lusetshenziselwa ukusika i-3-12 inch monocrystalline silicon, i-polycrystalline silicon, i-potassium arsenide, i-quartz crystal, njll. Izinto zokucubungula ubunjiniyela bemboni ye-solar photovoltaic, imboni ye-semiconductor kanye nemboni ye-piezoelectric crystal.Isetshenziswe kui-semiconductor, induku yombani, isici sesifunda, izinga lokushisa eliphezulu, umtshina we-ultraviolet, izinto zokwakha, i-astronomy, i-disc brake, i-clutch, isihlungi se-diesel particulate, i-filament pyrometer, ifilimu ye-ceramic, ithuluzi lokusika, into yokushisisa, uphethiloli wenuzi, ubucwebe, insimbi, okokuvikela, ukwesekwa kwe-catalyst neminye imikhakha
