Polysilicon ndi chiyani?

polysilicon ndi mawonekedwe a elemental silicon, yomwe ndi semiconductor zinthu zopangidwa ndi makhiristo angapo ang'onoang'ono ophatikizidwa pamodzi.

Pamene polysilicon ikhazikika pansi pa kuzizira kwakukulu, maatomu a silikoni amapangidwa mu mawonekedwe a diamondi ya diamondi kukhala ma nuclei ambiri a crystal. Ngati ma nuclei awa amakula kukhala njere zokhala ndi mawonekedwe osiyanasiyana a kristalo, njerezi zimaphatikizana kuti ziwonekere kukhala polysilicon. polysilicon ndiye zida zachindunji zopangira silicon ya monocrystalline ndipo imagwira ntchito ngati maziko azidziwitso pazida zamakono za semiconductor monga luntha lochita kupanga, kuwongolera zokha, kukonza zidziwitso, ndi kutembenuka kwazithunzi. Njira yokonzekera polysilicon nthawi zambiri ndikuyika silicon yosungunuka mu quartz crucible kenako ndikuyizizira pang'onopang'ono kuti ipange makhiristo angapo ang'onoang'ono panthawi yolimba. Kawirikawiri, kukula kwa makristasi a polysilicon okonzeka ndi ang'onoang'ono kuposa a silicon monocrystalline, kotero kuti magetsi ndi kuwala kwawo kudzakhala kosiyana pang'ono. Poyerekeza ndi silikoni ya monocrystalline, polysilicon imakhala ndi ndalama zochepa zopangira komanso kutembenuka kwazithunzi kwapamwamba, zomwe zimapangitsa kuti zigwiritsidwe ntchito kwambiri popanga mapanelo adzuwa. Kuphatikiza apo, polysilicon itha kugwiritsidwanso ntchito popanga zida za semiconductor ndi mabwalo ophatikizika.
