Silicon carbide (SiC)Cov khoom siv semiconductor yog cov paub tab tshaj plaws ntawm qhov dav band gap semiconductors tsim. SiC semiconductor cov ntaub ntawv muaj peev xwm siv tau zoo nyob rau hauv qhov kub thiab txias, siab zaus, siab zog, photoelectronics thiab hluav taws xob tiv thaiv cov cuab yeej vim lawv qhov sib txawv ntawm qhov sib txawv, siab tawg hluav taws xob, siab thermal conductivity, siab saturation electron txav thiab me me. Silicon carbide muaj ntau yam kev siv: vim nws qhov sib txawv ntawm qhov dav, nws tuaj yeem siv los ua lub teeb xiav-emitting diodes lossis ultraviolet detectors uas tsis tshua muaj kev cuam tshuam los ntawm tshav ntuj; Vim tias qhov hluav taws xob lossis hluav taws xob tuaj yeem zam tau yim zaug dua li silicon lossis gallium arsenide, tshwj xeeb tshaj yog tsim rau kev tsim cov khoom siv hluav taws xob high-voltage xws li high-voltage diodes, fais fab triode, silicon tswj thiab high-power microwave li; Vim tias qhov siab saturation electron migration ceev, tuaj yeem ua rau ntau yam khoom siv ntau zaus (RF thiab microwave);Silicon carbideyog cov khoom siv hluav taws xob zoo ntawm cov cua sov 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 thiab txias.
Raws li ib qho piv txwv tshwj xeeb, APEI tam sim no tab tom npaj los tsim nws qhov huab cua huab cua DC lub cev muaj zog rau NASA lub Venus Explorer (VISE) siv cov khoom siv silicon carbide. Tseem nyob rau theem tsim, lub hom phiaj yog txhawm rau tshawb nrhiav neeg hlau nyob rau saum npoo ntawm Venus.
Tsis tas li ntawd, silicon carbidemuaj zog ionic covalent daim ntawv cog lus, nws muaj siab hardness, thermal conductivity tshaj tooj liab, zoo tshav kub dissipation kev ua tau zoo, corrosion kuj muaj zog heev, hluav taws xob tsis kam, kub tsis kam thiab zoo tshuaj stability thiab lwm yam khoom, muaj ntau yam kev siv nyob rau hauv lub teb ntawm aerospace technology. Piv txwv li, kev siv cov khoom siv silicon carbide los npaj lub dav hlau rau cov neeg caij nkoj, cov neeg tshawb nrhiav nyob thiab ua haujlwm.
