Hauv kev siv hluav taws xob thiab semiconductor, qhov zoo ntawm SiC yog:
High thermal conductivity 120-270 W/mK
Tsawg coefficient ntawm thermal expansion 4.0x10^-6/degree
Qhov siab tshaj plaws tam sim no ceev
Kev sib xyaw ntawm peb tus yam ntxwv no muab SiC superior hluav taws xob conductivity, tshwj xeeb tshaj yog thaum piv rau silicon, SiC cov kwv tij nrov tshaj. Cov yam ntxwv ntawm SiC ua rau nws muaj txiaj ntsig zoo rau kev siv hluav taws xob siab uas yuav tsum muaj tam sim no, kub siab thiab siab thermal conductivity.
Nyob rau hauv xyoo tas los no, SiC tau dhau los ua tus neeg tseem ceeb hauv kev lag luam semiconductor, ua kom muaj zog MOSFETs, Schottky diodes thiab fais fab modules siv rau hauv high-power, high-performance applications. Txawm hais tias lawv kim dua silicon MOSFETs, uas feem ntau txwv rau qhov tawg ntawm 900 V, SiC tso cai rau qhov pib voltage ntawm ze li ntawm 10 kV.
SiC kuj tseem muaj kev hloov pauv qis heev thiab tuaj yeem tswj hwm kev ua haujlwm siab zaus, tso cai rau nws ua tiav kev ua haujlwm tsis sib xws rau hnub tim, tshwj xeeb tshaj yog hauv cov ntawv thov kev ua haujlwm ntawm qhov hluav taws xob ntau dua 600 volts. Thaum siv tau zoo, SiC cov cuab yeej tuaj yeem txo qhov kev hloov pauv thiab lub zog inverter poob los ntawm ze li ntawm 50%, qhov loj los ntawm 300%, thiab tag nrho cov nqi hluav taws xob los ntawm 20%. Qhov kev txo qis hauv tag nrho qhov loj me ua rau SiC muaj txiaj ntsig zoo hauv qhov hnyav thiab qhov chaw rhiab heev.
