Hais txog Silicon Carbide (SiC) Crystal
Silicon carbide (SiC), tseem hu ua carborundum, yog ib qho semiconductor uas muaj silicon thiab carbon nrog tshuaj formula SiC.SiC yog siv rau hauv cov khoom siv hluav taws xob semiconductor uas ua haujlwm ntawm qhov kub thiab txias, los yog ob qho tib si.SiC kuj yog ib qho tseem ceeb ntawm LED Cheebtsam, nws yog ib tug nrov substrate rau loj hlob GaN pab kiag li lawm, thiab nws kuj ua hauj lwm raws li ib tug tshav kub kis nyob rau hauv high- LEDs zog.
