Silicon carbide (SiC)Semiconductor abu ne mafi girma daya daga cikin fadi da band rata semiconductor ɓullo da. SiC semiconductor kayan suna da babban damar aikace-aikacen a cikin babban zafin jiki, babban mitar, babban iko, photoelectronics da na'urori masu jurewa radiation saboda faffadan band ɗin su, babban filin lantarki na rushewa, haɓakar yanayin zafi, babban motsi na lantarki da ƙarami. Silicon carbide yana da nau'ikan aikace-aikace: saboda faffadan tazarar bandeji, ana iya amfani da shi don yin diodes masu fitar da haske mai shuɗi ko na'urar gano hasken ultraviolet waɗanda hasken rana ke damun su; Domin ana iya jurewa wutar lantarki ko filin lantarki sau takwas fiye da siliki ko gallium arsenide, musamman dacewa da kera manyan na'urori masu ƙarfi irin su diodes masu ƙarfin lantarki, ƙarfin wutar lantarki, sarrafa silicon da na'urorin microwave masu ƙarfi; Saboda babban saturation na gudun hijirar lantarki, ana iya sanya shi cikin nau'ikan na'urori masu mitar mita (RF da microwave);Silicon carbideshi ne mai kyau shugaba na zafi da kuma gudanar da zafi fiye da kowane semiconductor abu, wanda ya sa silicon carbide na'urorin aiki a high yanayin zafi.
