i-sic coating i-Silicon carbide coating i-SiC coating egqunywe yi-Graphite substrate ye-Semiconductor

I-SiC ineempawu ezintle kakhulu zomzimba nezekhemikhali, ezifana nendawo yokunyibilika ephezulu, ubulukhuni obuphezulu, ukumelana nokugqwala kunye nokumelana ne-oxidation. Ingakumbi kuluhlu lwe-1800-2000 ℃, i-SiC inokumelana okuhle nokutsalwa kwenkunkuma. Ke ngoko, inamathuba amaninzi okusetyenziswa kwi-aerospace, izixhobo zezixhobo kunye nezinye iindawo. Nangona kunjalo, i-SiC ngokwayo ayinakusetyenziswa njengeisakhiwoizinto,ngoko ke indlela yokugquma idla ngokusetyenziswa ukusebenzisa ukumelana kwayo nokuguguleka kunye nokumelana nokukhuhlace.

I-silicon carbideIzixhobo ze-semiconductor (SIC) zesizukulwana sesithathueIzinto ze-miconductor zaphuhliswa emva kwezinto ze-semiconductor zesizukulwana sokuqala (i-Si, i-GE) kunye nezinto ze-semiconductor zesizukulwana sesibini (i-GaAs, i-gap, i-InP, njl.njl.). Njengezinto ze-semiconductor ze-wide band gap, i-silicon carbide ineempawu zobubanzi be-band gap enkulu, amandla entsimi yokuqhekeka okuphezulu, ukuhanjiswa kobushushu obuphezulu, isantya sokuhamba kwe-saturation esiphezulu, i-dielectric constant encinci, ukumelana nemitha enamandla kunye nozinzo oluhle lweekhemikhali. Ingasetyenziselwa ukuvelisa izixhobo ezahlukeneyo ze-high-frequency kunye namandla aphezulu anokumelana nobushushu obuphezulu kwaye ingasetyenziswa kwiimeko apho izixhobo ze-silicon zingasebenzi kakuhle, okanye zivelise isiphumo sokuba izixhobo ze-silicon kunzima ukuzivelisa kwizicelo ngokubanzi.

Eyona ndlela iphambili yokusebenza: isetyenziselwa ukusika ucingo lwe-silicon ye-monocrystalline engama-intshi ezi-3-12, i-silicon ye-polycrystalline, i-potassium arsenide, i-quartz crystal, njl. Izixhobo zokucubungula ubunjineli kwishishini le-photovoltaic yelanga, imboni ye-semiconductor kunye nemboni ye-piezoelectric crystal.Isetyenziswa kwii-semiconductor, intonga yombane, into yesekethe, ukusetyenziswa kobushushu obuphezulu, isixhobo sokufumanisa i-ultraviolet, izinto zokwakha, i-astronomy, i-disc brake, i-clutch, isihluzi se-diesel particulate, i-filament pyrometer, ifilimu yeseramikhi, isixhobo sokusika, into yokufudumeza, i-nuclear fuel, ubucwebe, intsimbi, izixhobo zokukhusela, inkxaso ye-catalyst kunye neminye imimandla
