Ihe dị iche n'etiti polililicon na monocrystalline silicon

Silicon ihe kacha mkpa na ụlọ ọrụ semiconductor. Usoro mmepụta dị mgbagwoju anya nke igwe na-arụ ọrụ semiconductor kwesịrị ịmalite site na mmepụta nke ihe silicon nke bụ isi.

Monocrystalline silicon anyanwụ gburugburu ọkụ

Monocrystalline silicon bụ ụdị nke Elumal silicon. Mgbe silicon elùllial silicon silicon na-eme ka ọ dị mma, a na-ahazi silicon atọmes na lattice lattice n'ọtụtụ kristal nuclei. Ọ bụrụ na Icleri ndị a na-eto eto na otu usoro nke ụgbọelu kristal, a ga-ejikọ ọka ndị a na myirịta na dilicrystalline silicon.

Monocrystalline silicon nwere akụkụ anụ ahụ nke a quasi-metal ma nwee ọnọdụ eletriki, nke na-abawanye na-abawanye ụba. N'otu oge ahụ, monocrystalline si sikicon nwekwara àgwà ọkara nke igwe eletriki. Ultra-dị ọcha si silicon bụ seminsic. A ga-eme ka ihe omume nke moltra-na-eme ihe na-adị ọcha silicon dị ọcha site na ịgbakwunye ihe chọta ⅲa (dịka boron), na pịsiki siliconductor nwere ike guzobere.
