Cov khoom siv semiconductor silicon carbide

Silicon carbide (SiC)Cov khoom siv semiconductor yog qhov paub tab tshaj plaws ntawm cov semiconductors dav dav uas tau tsim. Cov khoom siv semiconductor SiC muaj peev xwm siv tau zoo hauv kev kub siab, zaus siab, zog siab, photoelectronics thiab cov khoom siv tiv taus hluav taws xob vim lawv qhov dav dav, lub zog tawg siab, kev ua kom sov siab, kev txav mus los ntawm electron siab thiab qhov me me. Silicon carbide muaj ntau yam kev siv: vim nws qhov dav dav, nws tuaj yeem siv los ua cov diodes teeb xiav lossis cov khoom siv ultraviolet uas tsis tshua cuam tshuam los ntawm lub hnub ci; Vim tias lub zog lossis lub zog hluav taws xob tuaj yeem zam tau yim npaug dua li silicon lossis gallium arsenide, tshwj xeeb tshaj yog tsim rau kev tsim cov khoom siv hluav taws xob siab xws li cov diodes siab, lub zog triode, silicon tswj thiab cov khoom siv microwave siab; Vim tias qhov ceev ntawm electron migration siab, tuaj yeem ua rau ntau yam khoom siv zaus siab (RF thiab microwave);Silicon carbideyog ib qho khoom siv hluav taws xob zoo thiab ua kom sov zoo dua li lwm cov khoom siv semiconductor, uas ua rau cov khoom siv silicon carbide ua haujlwm ntawm qhov kub siab.

Ua piv txwv tshwj xeeb, APEI tam sim no tab tom npaj los tsim nws lub tshuab tsav DC ib puag ncig rau NASA's Venus Explorer (VISE) siv cov khoom siv silicon carbide. Tseem nyob rau theem tsim, lub hom phiaj yog kom tsaws cov neeg hlau tshawb nrhiav rau ntawm qhov chaw ntawm Venus.

Ntxiv rau, silicon carbidemuaj kev sib txuas ionic covalent muaj zog, nws muaj qhov nyuaj siab, thermal conductivity dua tooj liab, kev ua haujlwm zoo dissipation cua sov, corrosion tsis kam yog muaj zog heev, hluav taws xob tsis kam, kub tsis kam thiab tshuaj lom neeg ruaj khov thiab lwm yam khoom, muaj ntau yam kev siv hauv kev siv tshuab aerospace. Piv txwv li, kev siv cov ntaub ntawv silicon carbide los npaj cov dav hlau rau cov neeg caij nkoj, cov kws tshawb fawb nyob thiab ua haujlwm.
