Faahfaahinta Badeecada

Calaamadaha Alaabta

Graphite-ka Silicon waa walax isku dhafan oo carbide-ka silicon uu ku dheggan yahay dusha sare ee substrate-ka graphite. Waxay leedahay astaamo adag oo sare, xoog farsamo oo sare iyo iska caabin xirasho oo carbide-ka silicon ah, iyo sidoo kale sifooyinka is-salibiyeeya iyo iska caabinta shoogga kulaylka ee graphite. Waa agab isku-dhafan oo ku habboon iyo agab shaabad farsamo, oo ku habboon shaabadda farsamada ee bambooyinka biyaha ee kala duwan, bambooyinka saliidda, bambooyinka kiimikada, iyo boolal bambooyinka waaweyn ee xawaaraha sare iyo kuwa culus. Intaa waxaa dheer, graphite-ka silicon-ka leh wuxuu leeyahay iska caabin oksaydh oo wanaagsan, iska caabin shoogga kulaylka, dalool hoose, iyo koronto-qaadis gaar ah, waxaana loo isticmaali karaa agab sida walxaha birta ah ee dhalaaliya iyo tuubooyinka qabyada ah.

Halabuurka siliconeGraphite waa isku mid, dusha sarena waa la jaanqaadayaa gudaha, saamiga isku-dhafka ee carbide-ka silicon iyo graphite-ka waa la hagaajin karaa. Inta badan ee ku jirta carbide-ka silicon, ayaa cufnaanta walaxda sii kordheysa, xoogga cadaadiska ayaa sii kordhaya, iska caabintuna way sii kordheysaa.
