Sekepe sa silicon carbide wafer

Likarolo tsa Sehlahisoa sa SiC

Mocheso o phahameng le ho hanela ho bola, ho ntlafatsa boleng ba liphaphatha le tlhahiso

SiC e bua ka silicon carbide. Silicon carbide (SiC) e entsoe ka lehlabathe la quartz, coke le lisebelisoa tse ling tse tala ka ho qhibiliha ha sebōpi se phahameng sa mocheso. Tlhahiso ea hajoale ea indasteri ea silicon carbide e na le mefuta e 'meli, silicon carbide e ntšo le silicon carbide e tala. Ka bobeli ke kristale ea hexagonal, matla a khoheli a 3.21g / cm3, boima bo nyane ba 2840 ~ 3320kg / mm2.

Bonyane mefuta e 70 ea crystalline silicon carbide, ka lebaka la matla a eona a tlase a 3.21g / cm3 le matla a mocheso o phahameng, e loketse libere kapa lisebelisoa tse tala tsa sebōpi. khatello efe kapa efe e ke ke ea finyelloa, 'me e na le ts'ebetso e tlase haholo ea lik'hemik'hale.

Ka nako e ts'oanang, batho ba bangata ba lekile ho nkela silicon sebaka ka silicon carbide ka lebaka la conductivity ea bona e phahameng ea mocheso, matla a matla a tšimo ea motlakase le matla a phahameng a phahameng a hona joale. Haufinyane tjena, ts'ebelisong ea likarolo tsa matla a phahameng a semiconductor. Ha e le hantle, silicon carbide substrate ka conductivity ea mocheso, ka makhetlo a fetang 10 ho feta sapphire substrate, kahoo tšebeliso ea likaroloana tsa LED tsa silicon carbide, tse nang le conductivity e ntle le mocheso oa mocheso, o loketseng tlhahiso ea matla a phahameng a LED.
