Muraayadaha Indhaha ee SiC ee Nadiifka Sare leh Cabbirka 4H-semi-6SP oo la habeeyey Sawirka La Soo Bandhigay

Sharaxaad Gaaban:

Muraayadaha SiC (muraayadaha indhaha ee silicon carbide) waa qaybo indhaha oo sax ah oo laga sameeyay carbide silicon oo saafi ah (SiC), oo bixiya sifooyin jireed oo heer sare ah iyo waxqabadka indhaha. Iyagoo lagu garto isku-xidhka kulaylka aadka u sarreeya (490 W/m·K), isku-xidhka hoose ee ballaarinta kulaylka (4.0×10⁻⁶/K), iyo xasilloonida deegaanka ee heer sare ah, Muraayadaha SiC waxay noqdeen doorashada ugu fiican ee nidaamyada indhaha ee ka shaqeeya xaaladaha daran. Muraayadahani waxay muujiyaan waxqabad gudbin oo heer sare ah (gudbinta aan dahaarka lahayn >70%) oo ka gudba ultraviolet ilaa hirarka fog ee infrared (0.2-6 μm), taasoo ka dhigaysa kuwo si gaar ah ugu habboon nidaamyada laysarka awoodda sare leh, muraayadaha hawada sare, iyo sawir-qaadista indhaha ee deegaannada warshadaha ee adag.

Habka wax soo saarka ee muraayadaha SiC wuxuu ku lug leeyahay shiidid sax ah, nadiifin aad u sax ah, iyo daweyno gaar ah oo dahaadh ah si loo gaaro dusha sare ee indhaha oo leh saxnaanta nanoscale (qafiifnimada dusha sare <1 nm). Joomatari gaar ah oo ay ku jiraan dusha sare ee aspheric iyo freeform ayaa la samayn karaa si loo daboolo shuruudaha naqshadeynta ee nidaamyada indhaha ee saxnaanta sare leh.
