Masu ɗaukar siki mai rufi na SiC, sic shafi, SiC shafi mai rufi na graphite substrate don semiconductor

An yi wa silicon carbide fentiFaifan graphite shine don shirya layin kariya na silicon carbide akan saman graphite ta hanyar adana tururi na zahiri ko na sinadarai da feshi. Ana iya haɗa layin kariya na silicon carbide da matrix na graphite sosai, wanda ke sa saman tushen graphite ya yi kauri kuma babu gurɓatattun abubuwa, yana ba matrix na graphite halaye na musamman, gami da juriyar oxidation, juriyar acid da alkali, juriyar yashewa, juriyar tsatsa, da sauransu. A halin yanzu, rufin Gan yana ɗaya daga cikin mafi kyawun abubuwan da ke cikin tushen epitaxial na silicon carbide.

Semiconductor na silicon carbide shine babban kayan da aka ƙera na semiconductor mai faɗi da faɗi. Na'urorinsa suna da halaye na juriyar zafi mai yawa, juriyar ƙarfin lantarki mai yawa, mita mai yawa, ƙarfin lantarki mai yawa da juriyar radiation. Yana da fa'idodin saurin sauyawa da inganci mai yawa. Yana iya rage yawan amfani da wutar lantarki na samfura sosai, inganta ingancin canza makamashi da rage yawan samfura. Ana amfani da shi galibi a cikin sadarwa ta 5g, tsaro na ƙasa da masana'antar soja. Filin RF wanda aka wakilta ta hanyar sararin samaniya da filin lantarki mai ƙarfi wanda sabbin motocin makamashi da "sabbin ababen more rayuwa" ke wakilta suna da fa'idodi masu kyau da yawa a kasuwa a fannonin farar hula da na soja.

Substrate na silicon carbide shine babban kayan da aka ƙera a cikin sabon semiconductor mai faɗi da faɗi. Ana amfani da substrate na silicon carbide galibi a cikin microwave electronics, power electronics da sauran fannoni.Yana a ƙarshen gaba na sarkar masana'antar semiconductor mai faɗi kuma shine kayan maɓalli na asali. Ana iya raba silikon carbide zuwa nau'i biyu: semi insulating da conductive. Daga cikinsu, silikon carbide mai semi insulating yana da juriya mai yawa (resisivity ≥ 105 Ω· cm). Silikon rufi tare da takardar epitaxial na gallium nitride iri-iri ana iya amfani da shi azaman kayan na'urorin RF, wanda galibi ana amfani da shi a cikin sadarwa ta 5g, tsaro na ƙasa da masana'antar soja a cikin abubuwan da ke sama; ɗayan kuma silikon carbide mai conductive tare da ƙarancin juriya (zagayen juriya shine 15 ~ 30m Ω· cm). Ana iya amfani da silikon carbide mai kama da silikon carbide mai conductive da silikon carbide azaman kayan na'urorin wutar lantarki. Babban yanayin aikace-aikacen shine motocin lantarki, tsarin wutar lantarki da sauran fannoni.
