Tilmaamaha Alaabta SiC
Heerkulka sare iyo u adkaysiga daxalka, hagaajinta tayada waferka iyo wax soo saarka
SiC waxaa loola jeedaa carbide silicon.Silicon carbide (SiC) waxay ka samaysan tahay ciid quartz, kookaha iyo alaabada kale ee cayriin iyada oo loo marayo dhalaalidda foornada heerkul sare.Wax soo saarka warshadaha hadda ee carbide silicon wuxuu leeyahay laba nooc, carbide silicon madow iyo carbide silicon cagaaran.Labaduba waa crystal hexagonal, culeyska gaarka ah ee 3.21g / cm3, qallafsanaanta micro ee 2840 ~ 3320kg / mm2.
Ugu yaraan 70 nooc oo ah silikoon carbide crystalline, sababtoo ah cuf-jiidad hooseeya 3.21g/cm3 iyo xoogga heerkulka sare, waxay ku habboon tahay xargaha ama heerkulka sare ee alaabta ceeriin.cadaadis kasta lama gaadhi karo, oo waxay leeyihiin hawl yar oo kiimiko ah.
Isla mar ahaantaana, dad badan ayaa isku dayay in ay ku beddelaan silikoon leh carbide silikoon sababtoo ah kuleylka kuleylka sarreeya, xoogga sare ee korantada iyo cufnaanta ugu sareysa ee hadda.Dhawaan, in codsiga ee qaybaha awoodda sare ee semiconductor.Dhab ahaantii, substrate-ka silikoon carbide ee conductivity kaamerada, in ka badan 10 jeer ka sarreeya substrate sapphire, sidaas isticmaalka qalabka silikon carbide substrate LED qaybaha, la conductivity wanaagsan iyo kulaylka, xad ku haboon in wax soo saarka ee LED awood sare.
