Silikon carbide (SiC)Kayan semiconductor shine mafi girma daga cikin semiconductors masu girman rata mai faɗi da aka haɓaka. Kayan semiconductor na SiC suna da babban damar amfani a cikin yanayin zafi mai yawa, mita mai yawa, babban iko, na'urori masu jure wa radiation saboda girman rata mai faɗi, filin lantarki mai lalacewa, babban ƙarfin lantarki, babban motsi na electron mai cikawa da ƙaramin girma. Silicon carbide yana da aikace-aikace iri-iri: saboda faɗin rata mai faɗi, ana iya amfani da shi don yin diodes masu fitar da haske shuɗi ko na'urorin gano hasken ultraviolet waɗanda hasken rana ba ya shafar su sosai; Saboda ƙarfin lantarki ko filin lantarki ana iya jure su sau takwas fiye da silicon ko gallium arsenide, musamman ya dace da ƙera na'urori masu ƙarfin lantarki mai girma kamar diodes masu ƙarfin lantarki, triode mai ƙarfi, silicon mai sarrafawa da na'urorin microwave masu ƙarfi; Saboda saurin ƙaura mai yawa na electron mai cikawa, ana iya yin su zuwa na'urori masu yawan mita (RF da microwave);Silicon carbideyana da kyau wajen sarrafa zafi kuma yana gudanar da zafi fiye da kowane kayan semiconductor, wanda hakan ke sa na'urorin silicon carbide su yi aiki a yanayin zafi mai yawa.
