Kev Piav Qhia Luv:

Silicon carbide (SiC) yog cov khoom siv semiconductor dav dav uas muaj kev ua tau zoo heev ntawm thermal conductivity thiab kev ruaj khov tshuaj lom neeg.6H-Nqhia tias nws cov qauv siv lead ua yog hexagonal (6H), thiab "N" qhia tias nws yog cov khoom siv semiconductor N-hom, uas feem ntau ua tiav los ntawm kev doping nitrogen.
Lub silicon carbide substrate muaj cov yam ntxwv zoo heev ntawm kev tiv taus siab, kev tiv taus kub siab, kev ua haujlwm siab zaus, thiab lwm yam. Piv nrog cov khoom silicon, lub cuab yeej npaj los ntawm silicon substrate tuaj yeem txo qhov poob los ntawm 80% thiab txo qhov loj ntawm lub cuab yeej los ntawm 90%. Hauv cov tsheb fais fab tshiab, silicon carbide tuaj yeem pab cov tsheb fais fab tshiab ua tiav qhov sib dua thiab txo qhov poob, thiab nce qhov tsav tsheb ntau; Hauv kev sib txuas lus 5G, nws tuaj yeem siv rau kev tsim cov khoom siv cuam tshuam; Hauv kev tsim hluav taws xob photovoltaic tuaj yeem txhim kho kev hloov pauv zoo; Hauv kev thauj mus los ntawm tsheb ciav hlau tuaj yeem siv nws cov yam ntxwv kub siab thiab siab siab.
