Cov Khoom Siv Hloov Yav Tom Ntej

Silicon carbide (SiC) yog ib yam khoom siv semiconductor tshiab. Silicon carbide muaj qhov sib txawv loj (kwv yees li 3 npaug ntawm silicon), lub zog tseem ceeb ntawm thaj chaw (kwv yees li 10 npaug ntawm silicon), kev ua kom sov siab (kwv yees li 3 npaug ntawm silicon). Nws yog ib yam khoom siv semiconductor tseem ceeb rau tiam tom ntej. SiC coatings siv dav hauv kev lag luam semiconductor thiab hnub ci photovoltaics. Tshwj xeeb, cov susceptors siv hauv kev loj hlob epitaxial ntawm LEDs thiab Si ib leeg siv lead ua epitaxy xav tau kev siv SiC coating. Vim yog qhov sib txawv ntawm LEDs hauv kev lag luam teeb pom kev zoo thiab kev tso saib, thiab kev loj hlob ntawm kev lag luam semiconductor,Cov khoom siv SiC txheejkev cia siab zoo heev.
