Iyini i-polysilicon?

i-polysilicon iwuhlobo lwe-silicon eyisisekelo, okuyingxenye ye-semiconductor eyakhiwe amakristalu amancane amaningi ahlanganiswe ndawonye.

Lapho i-polysilicon iqina ngaphansi kwezimo ezipholile kakhulu, ama-athomu e-silicon ahlela ngendlela ye-lattice yedayimane abe ama-nuclei amaningi ekristalu. Uma lezi nuclei zikhula zibe izinhlamvu ezinomumo ohlukile wekristalu, lezi zinhlamvu zihlangana ukuze zicwebezele zibe yi-polysilicon. i-polysilicon iyimpahla eqondile eqondile yokukhiqiza i-silicon ye-monocrystalline futhi isebenza njengesisekelo solwazi lwe-elekthronikhi kumadivayisi wesimanje we-semiconductor njengobuhlakani bokwenziwa, ukulawula okuzenzakalelayo, ukucutshungulwa kolwazi, nokuguqulwa kwesithombe sikagesi. Indlela yokulungiselela ye-polysilicon ngokuvamile iwukubeka i-silicon encibilika ku-crucible ye-quartz bese ipholisa kancane ukuze yakhe amakristalu amancane amaningi phakathi nenqubo yokuqinisa. Ngokuvamile, ubukhulu bamakristalu e-polysilicon alungiselelwe buncane kune-silicon ye-monocrystalline, ngakho izakhiwo zabo zikagesi neze-optical zizohluka kancane. Uma kuqhathaniswa ne-silicon ye-monocrystalline, i-polysilicon inezindleko zokukhiqiza eziphansi kanye nokusebenza kahle okuphezulu kokuguqulwa kwe-photoelectric, okwenza isetshenziswe kabanzi ekukhiqizeni amaphaneli elanga. Ngaphezu kwalokho, i-polysilicon ingasetshenziswa futhi ekukhiqizeni amadivaysi e-semiconductor namasekethe ahlanganisiwe.
