Silicon carbide (SiC) mea tioata tasi o loʻo i ai le lautele o le va tele (~ Si 3 taimi), conductivity vevela maualuga (~ Si 3.3 taimi po o GaAs 10 taimi), maualuga electron saturation fua faatatau (~ Si 2.5 taimi), eletise malepe maualuga. fanua (~ Si 10 taimi po o GaAs 5 taimi) ma isi uiga mataʻina.
Semicera malosi e mafai ona tuʻuina atu i tagata faʻatau le tulaga maualuga Conductive (Conductive), Semi-insulating (Semi-insulating), HPSI (High Purity semi-insulating) silicon carbide substrate; E le gata i lea, e mafai ona matou tuʻuina atu i tagata faʻatau i le tutusa ma le heterogeneous silicon carbide epitaxial sheets; E mafai foi ona matou faʻavasegaina le pepa epitaxial e tusa ai ma manaʻoga faʻapitoa o tagata faʻatau, ma e leai se faʻatonuga maualalo.
