I-SiC egqunywe

I-VET ENERGY, umenzi ophambili we-CVD SIC coating eTshayina

Izinto ezisetyenziswayo zitshintsha ikamva

I-Silicon carbide (i-SiC) yinto entsha ye-semiconductor edityanisiweyo. I-Silicon carbide ine-band gap enkulu (malunga ne-silicon ephindwe kathathu), amandla aphezulu entsimi abalulekileyo (malunga ne-silicon ephindwe kalishumi), ukuhanjiswa kobushushu okuphezulu (malunga ne-silicon ephindwe kathathu). Yinto ebalulekileyo ye-semiconductor yesizukulwana esilandelayo. Iingubo ze-SiC zisetyenziswa kakhulu kushishino lwe-semiconductor kunye ne-solar photovoltaics. Ngokukodwa, ii-susceptors ezisetyenziswa ekukhuleni kwe-epitaxial kwee-LED kunye ne-Si single crystal epitaxy zifuna ukusetyenziswa kwe-SiC coating. Ngenxa yokunyuka okunamandla kwee-LED kushishino lokukhanyisa nokubonisa, kunye nophuhliso olunamandla kushishino lwe-semiconductor,Imveliso yokugquma yeSiCamathuba amahle kakhulu.
