Cov Khoom Siv Qhia Txog Khoom
Silicon carbide (SiC) yog ib yam khoom siv sib xyaw ua ke uas muaj cov ntsiab lus carbon thiab silicon, thiab yog ib qho ntawm cov khoom siv zoo tshaj plaws rau kev ua cov khoom siv kub, zaus siab, zog siab thiab hluav taws xob siab. Piv nrog cov khoom siv silicon ib txwm muaj (Si), qhov dav txwv ntawm silicon carbide yog peb npaug ntawm silicon; qhov thermal conductivity yog 4-5 npaug ntawm silicon; qhov tawg voltage yog 8-10 npaug ntawm silicon; thiab qhov electron saturation drift rate yog 2-3 npaug ntawm silicon, uas ua tau raws li qhov xav tau ntawm kev lag luam niaj hnub rau lub zog siab, voltage siab, thiab zaus siab, thiab nws feem ntau yog siv los ua cov khoom siv hluav taws xob ceev ceev, zaus siab, zog siab thiab lub teeb ci, thiab nws cov chaw siv downstream suav nrog smart grid, Tsheb zog tshiab, photovoltaic cua fais fab, 5G kev sib txuas lus, thiab lwm yam. Hauv kev lag luam ntawm cov khoom siv fais fab, silicon carbide diodes thiab MOSFETs tau pib siv rau kev lag luam.
Cov txiaj ntsig ntawm SiC wafers / SiC substrate
Kev tiv taus kub siab. Qhov dav ntawm silicon carbide yog 2-3 npaug ntawm silicon, yog li cov electrons tsis tshua dhia ntawm qhov kub siab thiab tuaj yeem tiv taus qhov kub siab dua, thiab qhov thermal conductivity ntawm silicon carbide yog 4-5 npaug ntawm silicon, ua rau nws yooj yim dua los dissipate cua sov ntawm lub cuab yeej thiab tso cai rau qhov kub siab dua. Cov yam ntxwv kub siab tuaj yeem ua rau lub zog ceev dua, thaum txo qhov xav tau rau lub kaw lus dissipation cua sov, ua rau lub davhlau ya nyob twg sib dua thiab me dua.
Kev tiv taus hluav taws xob siab. Lub zog tawg ntawm Silicon carbide yog 10 npaug ntawm silicon, ua rau nws tiv taus cov hluav taws xob siab dua, ua rau nws tsim nyog dua rau cov khoom siv hluav taws xob siab.
Kev tiv thaiv zaus siab. Silicon carbide muaj ob npaug ntawm qhov ceev ntawm electron drift ntawm silicon, ua rau nws cov khoom siv tsis muaj qhov teeb meem rub tam sim no hauv cov txheej txheem kaw, tuaj yeem txhim kho qhov zaus hloov pauv ntawm lub cuab yeej, kom ua tiav qhov me me ntawm lub cuab yeej.
Kev poob zog tsawg. Silicon carbide muaj qhov tsis kam tiv thaiv tsawg heev piv rau cov khoom siv silicon, kev poob conduction tsawg; tib lub sijhawm, qhov bandwidth siab ntawm silicon carbide txo qhov tam sim no xau thiab poob zog; ntxiv rau, cov khoom siv silicon carbide hauv cov txheej txheem kaw tsis muaj qhov tshwm sim rub tam sim no, kev poob hloov qis.
