Silicon carbide (SiC) single crystal material ine bhendi hombe gap upamhi (~Si 3 nguva), high thermal conductivity (~Si 3.3 nguva kana GaAs ka10), high electron saturation migration rate (~Si 2.5 times), high breakdown magetsi munda (~ Si 10 nguva kana GaAs 5 nguva) uye mamwe maitiro akatanhamara.
Semicera simba rinogona kupa vatengi nemhando yepamusoro Conductive (Conductive), Semi-insulating (Semi-insulating), HPSI (High Purity semi-insulating) silicon carbide substrate; Mukuwedzera, tinogona kupa vatengi vane homogeneous uye heterogeneous silicon carbide epitaxial sheets; Isu tinogona zvakare kugadzirisa iyo epitaxial pepa zvinoenderana nezvinodiwa chaizvo nevatengi, uye hapana hushoma hwekurongeka huwandu.
