Uhi ʻia ʻo SiC

ʻO VET ENERGY, ka mea hana alakaʻi o ka uhi ʻana o CVD SIC ma Kina

Hoʻololi nā mea hana i ka wā e hiki mai ana

ʻO Silicon carbide (SiC) kahi mea semiconductor hui hou. Loaʻa i ka Silicon carbide kahi ākea band nui (ma kahi o 3 mau manawa silicon), ikaika kahua koʻikoʻi kiʻekiʻe (ma kahi o 10 mau manawa silicon), conductivity thermal kiʻekiʻe (ma kahi o 3 mau manawa silicon). He mea semiconductor hanauna hou koʻikoʻi ia. Hoʻohana nui ʻia nā uhi SiC i ka ʻoihana semiconductor a me nā photovoltaics solar. Ma ke ʻano kūikawā, ʻo nā susceptors i hoʻohana ʻia i ka ulu ʻana o ka epitaxial o nā LED a me ka epitaxy kristal hoʻokahi Si e pono ai ka hoʻohana ʻana i ka uhi SiC. Ma muli o ke ʻano ikaika o nā LED i ka ʻoihana kukui a me ka hōʻike, a me ka hoʻomohala ikaika o ka ʻoihana semiconductor,Huahana uhi SiCmaikaʻi loa nā manaʻolana.
