Ukwaleka kwe-sic I-Silicon carbide iyalekwa I-SiC egqunywe nge-Graphite substrate yeSemiconductor

I-SiC ineempawu ezibalaseleyo zomzimba kunye neekhemikhali, njengendawo ephezulu yokunyibilika, ukuqina okuphezulu, ukuchasana nokugqwala kunye nokumelana ne-oxidation. Ngokukodwa kuluhlu lwe-1800-2000 ℃, i-SiC inokumelana nokukhupha okulungileyo. Ke ngoko, inamathemba osetyenziso olubanzi kwi-aerospace, izixhobo zezixhobo kunye neminye imimandla. Nangona kunjalo, iSiC ngokwayo ayinakusetyenziswa njengeisakhiwoimpahla,ngoko ke indlela yokwaleka idla ngokusetyenziswa ukwenza ukusetyenziswa kokumelana nokunxitywa kwayo kunye ne-ablation resistance.

I-silicon carbide(SIC) izinto ze-semiconductor sisizukulwana sesithathu seizinto ze-miconductor eziphuhliswe emva kwesizukulwana sokuqala se-semiconductor material (Si, GE) kunye nesizukulwana sesibini se-semiconductor impahla (i-GaAs, i-gap, i-InP, njl.). Njengomda obanzi we-gap semiconductor, i-silicon carbide ineempawu zobubanzi bebhendi enkulu, ukomelela kwebala lokuqhekeka okuphezulu, ukuguquguquka okuphezulu kwe-thermal, isantya esiphezulu se-saturation drift, i-dielectric encinci engaguqukiyo, ukuxhathisa okunamandla kwimitha kunye nokuzinza okuhle kweekhemikhali. Ingasetyenziselwa ukuvelisa izixhobo ezahlukeneyo ze-high-frequency kunye ne-high-power-high-high-high-high resistance resistance kwaye ingasetyenziselwa kwiimeko apho izixhobo ze-silicon zingenakho, Okanye zivelise umphumo wokuba izixhobo ze-silicon zinzima ukuvelisa kwizicelo eziqhelekileyo.

Isicelo esiphambili: isetyenziselwa ukusika ucingo lwe-3-12 intshi ye-silicon ye-monocrystalline, i-silicon ye-polycrystalline, i-potassium arsenide, i-quartz crystal, njl. Izinto zokulungisa ubunjineli kwishishini le-solar photovoltaic, imboni ye-semiconductor kunye ne-piezoelectric crystal industry.Isetyenziswa kwiisemiconductor, intonga yombane, intonga yesekethe, ubushushu obuphezulu besicelo, i-ultraviolet detector, izinto zokwakha, i-astronomy, i-disc brake, i-clutch, i-diesel particulate filter, i-filament pyrometer, ifilimu ye-ceramic, isixhobo sokusika, into yokufudumeza, i-nuclear fuel, ubucwebe, intsimbi, izixhobo zokukhusela, inkxaso yecatalyst kunye nezinye iinkalo
