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.
Ko nga taputapu SiC he painga kaore e taea te whakakapi i roto i te waahi o te pāmahana teitei, te pehanga teitei, te auau teitei, nga taputapu hiko hiko me nga tono taiao tino nui penei i te aerospace, te hoia, te kaha karihi, me era atu, hei hanga i nga hapa o nga taputapu taputapu semiconductor tuku iho. tono, a kei te huri haere hei auraki o te hiko hiko.
