silicon carbide (SiC) yog hluav taws xob conductive, tab sis nws cov conductivity tuaj yeem sib txawv nyob ntawm nws cov doping thiab daim ntawv tshwj xeeb ntawm SiC. SiC yog ib qho semiconductor, uas txhais tau hais tias nws cov hluav taws xob conductivity tuaj yeem tswj tau los ntawm kev qhia impurities (doping) rau hauv nws cov qauv siv lead ua.
Muaj ntau hom SiC crystals, xws li n-type thiab p-type:
N-type SiC: Doping nrog cov ntsiab lus xws li phosphorus lossis nitrogen qhia ntxiv electrons, txhim kho nws cov conductivity.
P-type SiC: Doping nrog cov ntsiab lus xws li txhuas lossis boron tuaj yeem tsim "qhov" (cov cab kuj zoo) uas tseem ua rau hluav taws xob conductivity.
