Silicon carbide (SiC) rauemi karaihe kotahi he nui te whanui aputa ropu (~ Si 3 wa), te kawe waiariki tiketike (~ Si 3.3 wa GaAs 10 wa ranei), tiketike irahiko waiwai auau hekenga (~ Si 2.5 wa), hiko pakaru tiketike mara (~Si 10 wa ranei GaAs 5 wa) me etahi atu ahuatanga tino pai.
Ka taea e te kaha Semicera te whakarato i nga kaihoko ki te Conductive (Conductive), Semi-insulating (Semi-insulating), HPSI (High Purity semi-insulating) silicon carbide substrate; I tua atu, ka taea e matou te whakarato i nga kaihoko ki nga pepa epitaxial silicon carbide homogeneous me te heterogeneous; Ka taea hoki e matou te whakarite i te pepa epitaxial kia rite ki nga hiahia motuhake o nga kaihoko, a kaore he iti rawa o te tono.
