Kedu ihe bụ polysilicon?

polysilicon bụ ụdị silicon elemental, nke bụ ihe semiconductor mejupụtara ọtụtụ obere kristal gbakọtara ọnụ.

Mgbe polysilicon gbasiri ike n'okpuru ọnọdụ jụrụ oyi, atom silicon na-ahazi n'ụdị lattice diamond n'ime ọtụtụ oghere kristal. Ọ bụrụ na nuclei ndị a na-etolite n'ọka nwere ntụgharị kristal dị iche iche, mkpụrụ osisi ndị a na-ejikọta ka ọ bụrụ polysilicon. polysilicon bụ ngwa ngwa maka imepụta silicon monocrystalline ma na-eje ozi dị ka ihe ntọala ozi eletrọnịkị maka ngwaọrụ semiconductor nke oge a dị ka ọgụgụ isi, njikwa akpaka, nhazi ozi na ntụgharị foto. Usoro nkwadebe nke polysilicon na-abụkarị site n'itinye silicon na-agbaze na quartz crucible wee jiri nwayọọ nwayọọ mee ka ọ dị jụụ ka ọ bụrụ ọtụtụ obere kristal n'oge usoro siri ike. Ọtụtụ mgbe, nha kristal polysilicon a kwadebere dị obere karịa nke silicon monocrystalline, yabụ akụrụngwa eletrik na ngwa anya ha ga-adịtụ iche. E jiri ya tụnyere silicon monocrystalline, polysilicon nwere ọnụ ahịa mmepụta dị ala yana arụmọrụ ngbanwe fotoelectric dị elu, na-eme ka a na-eji ya eme ihe n'ọtụtụ ebe na mmepụta nke mbara igwe. Tụkwasị na nke ahụ, a pụkwara iji polysilicon mee ihe n'ichepụta ngwaọrụ semiconductor na sekit jikọtara ọnụ.
