Cov ntaub ntawv hloov lub neej yav tom ntej

Silicon carbide (SiC) yog cov khoom siv semiconductor tshiab. Silicon carbide muaj qhov sib txawv loj (kwv yees li 3 zaug silicon), lub zog tseem ceeb heev (li 10 npaug silicon), siab thermal conductivity (kwv yees li 3 zaug silicon). Nws yog ib qho tseem ceeb ntawm cov khoom siv semiconductor tom ntej. SiC coatings yog siv dav hauv kev lag luam semiconductor thiab hnub ci photovoltaics. Hauv particular, cov susceptors siv nyob rau hauv epitaxial kev loj hlob ntawm LEDs thiab Si ib leeg siv lead ua epitaxy yuav tsum tau siv SiC txheej. Vim muaj zog nce siab ntawm LEDs hauv kev lag luam teeb pom kev zoo thiab kev lag luam, thiab kev loj hlob ntawm kev lag luam semiconductor,SiC txheej khoomkev cia siab yog zoo heev.
