Yintoni i-polysilicon?

i-polysilicon luhlobo lwe-silicon ye-elemental, eyimpahla ye-semiconductor eyenziwe ngeekristale ezincinci ezininzi ezidityanisiweyo.

Xa i-polysilicon iqina phantsi kweemeko zokupholisa okukhulu, iiathom ze-silicon zilungelelaniswa kwifomu yelathisi yedayimani kwiinuclei ezininzi zekristale. Ukuba ezi nuclei zikhula zibe ziinkozo ezinemikhombandlela eyahlukileyo yekristale, ezi nkozo ziyadibana ukuze zikhanye zibe yipolysilicon. i-polysilicon yimathiriyeli ekrwada ngokuthe ngqo yokuvelisa isilicon ye-monocrystalline kwaye isebenza njengesiseko solwazi lwe-elektroniki kwizixhobo zangoku ze-semiconductor ezifana nobukrelekrele bokwenziwa, ulawulo oluzenzekelayo, ukusetyenzwa kolwazi, kunye noguqulo lombane. Indlela yokulungiselela i-polysilicon ngokubanzi ngokubeka i-silicon inyibilika kwi-quartz crucible kwaye emva koko ipholise ngokucothayo ukwenza iikristale ezincinci ezininzi ngexesha lenkqubo yokuqina. Ngokuqhelekileyo, ubukhulu beekristali ze-polysilicon ezilungiselelwe zincinci kune-silicon ye-monocrystalline, ngoko ke iipropati zabo zombane kunye ne-optical ziyahluka kancinci. Xa kuthelekiswa ne-silicon ye-monocrystalline, i-polysilicon ineendleko eziphantsi zokuvelisa kunye nokusebenza okuphezulu kokuguqulwa kwe-photoelectric, okwenza ukuba isetyenziswe ngokubanzi kwimveliso yeepaneli zelanga. Ukongeza, i-polysilicon ingasetyenziselwa ukwenziwa kwezixhobo ze-semiconductor kunye neesekethe ezidibeneyo.
