Qalabka Semiconductor-ka ee silikoon carbide

Silikoon carbide (SiC)Maaddada semiconductor-ka ayaa ah tan ugu bislaaday semiconductor-yada farqiga ballaaran ee la sameeyay. Maaddooyinka semiconductor-ka ee SiC waxay leeyihiin awood codsi oo weyn heerkulka sare, soo noqnoqoshada sare, awoodda sare, qalabka sawir-qaadista iyo qalabka u adkaysta shucaaca sababtoo ah farqiga ballaaran ee band-ka, goobta korantada ee burburka sare, socodka kulaylka sare, dhaqdhaqaaqa elektarooniga ee buuxsama iyo cabbir yar. Silicon carbide waxay leedahay codsiyo badan: sababtoo ah farqiga ballaaran ee band-ka, waxaa loo isticmaali karaa in lagu sameeyo diode-yada iftiinka buluugga ah ama dareemayaasha ultraviolet-ka oo si dhib yar u saameeya iftiinka qorraxda; Sababtoo ah danabka ama goobta korontada waxaa loo dulqaadan karaa siddeed jeer marka loo eego silicon ama gallium arsenide, gaar ahaan ku habboon soo saarista aaladaha awoodda sare ee danabka sare sida diode-yada danabka sare, triode-ka awoodda, qalabka xakamaynta silicon iyo qalabka microwave-ka awoodda sare leh; Sababtoo ah xawaaraha socdaalka elektarooniga ee buuxsama ee sare, waxaa loo samayn karaa qalab kala duwan oo soo noqnoqosha sare leh (RF iyo microwave);Kaarboohaydraytka silikoonka ahwaa gudbiye wanaagsan oo kulaylka ah wuxuuna kulaylka si ka wanaagsan u qabtaa marka loo eego walxaha kale ee semiconductor-ka, taasoo ka dhigaysa aaladaha silicon carbide inay ku shaqeeyaan heerkul sare.

Tusaale ahaan, APEI hadda waxay isu diyaarinaysaa inay horumariso nidaamkeeda wadista matoorka DC ee deegaanka aadka u daran ee loogu talagalay Venus Explorer (VISE) ee NASA iyadoo la adeegsanayo qaybaha silicon carbide. Wali marxaladda naqshadeynta, yoolku waa in robotyada sahaminta lagu dejiyo dusha sare ee Venus.

Intaa waxaa dheer, scarbide-ka iliconWaxay leedahay isku xidhnaan xooggan oo ionic covalent ah, waxay leedahay adkeysi sare, kulayl-qaadis ka badan naxaasta, waxqabad wanaagsan oo kala-baxa kulaylka, iska caabbinta daxalka waa mid aad u xoog badan, iska caabbinta shucaaca, iska caabbinta heerkulka sare iyo xasilloonida kiimikada ee wanaagsan iyo sifooyin kale, waxay leedahay codsiyo badan oo ku saabsan teknoolojiyadda hawada sare. Tusaale ahaan, isticmaalka agabka silicon carbide si loogu diyaariyo dayax-gacmeedka hawada sare ee cirbixiyeennada, cilmi-baarayaasha si ay u noolaadaan oo u shaqeeyaan.
