Qalabka semiconductor ee Silicon carbide

Silikon carbide (SiC)Qalabka semiconductor waa midka ugu bisil ee ka mid ah semiconductor-ka farqiga ballaaran ee la sameeyay. Qalabka semiconductor ee SiC waxay leeyihiin awood codsi heer sare ah oo heerkul sare ah, soo noqnoqoshada sare, awood sare, qalabka elektiroonigga ah iyo aaladaha u adkeysiga shucaaca sababtoo ah faraqa ballaaran ee band-ga, beer koronto oo burbursan, kuleylka sare ee kuleylka, dhaqdhaqaaqa elektaroonigga sare ee saturation iyo cabbir yar. Silicon carbide waxay leedahay codsiyo kala duwan oo kala duwan: sababtoo ah farqiga ballaaran ee band, waxaa loo isticmaali karaa in lagu sameeyo muraayadaha iftiinka buluuga ah ama qalabka ultraviolet oo si dhib yar u saameeya iftiinka qorraxda; Sababtoo ah korantada ama goobta korantada ayaa loo dulqaadan karaa siddeed jeer silikoon ama gallium arsenide, gaar ahaan ku habboon soo saarista qalabka tamarta sare ee tamarta sare leh sida diodes-voltage-ka sare, triode korantada, silicon la xakameeyey iyo qalabka microwave-ka ee awoodda sare leh; Sababtoo ah xawaaraha guuritaanka elektarooniga ah ee saturation sare, waxaa laga dhigi karaa noocyo kala duwan oo ah aaladaha soo noqnoqda sare (RF iyo microwave);Silikoon carbidewaa kaari fiican ee kulaylka iyo qabata kulaylka si ka fiican wax kasta oo semiconductor kale, taas oo ka dhigaysa qalabka silicon carbide shaqeeyaan heerkul sare.

Tusaale gaar ah, APEI waxay hadda isku diyaarinaysaa inay horumariso deegaankeeda durugsan ee nidaamka wadista baabuurta ee NASA's Venus Explorer (VISE) iyadoo adeegsanaysa qaybaha silikoon carbide. Weli marxaladda naqshadeynta, hadafku waa in dhulka la dhigo robots sahaminta dusha Venus.

Intaa waxaa dheer, scarbidhidwuxuu leeyahay dammaanad covalent ionic xoog leh, waxa uu leeyahay engegnaantiisa sare, conductivity kaamerada ka badan copper, wax qabad kulaylka wanaagsan, iska caabin daxalka waa mid aad u xoog badan, iska caabin shucaaca, caabin heerkulka sare iyo xasiloonida kiimikada wanaagsan iyo guryaha kale, leeyahay tiro balaadhan oo ah codsiyada in garoonka tignoolajiyada hawada sare. Tusaale ahaan, isticmaalka qalabka silikoon carbide si loogu diyaariyo hawada sare ee cirbixiyeenada, cilmi-baarayaasha si ay u noolaadaan oo ay u shaqeeyaan.
