Umahluko phakathi kwePolysilicon kunye ne-monocrystalline silicon

Izixhobo ze-Silicon yeyona nto isisiseko neyona nto iphambili kumzi-mveliso we-semicondcuctor. Inkqubo yemveliso yentsokothi ye-semicondcuctor yeshishini kufuneka iqale ngokuveliswa kwemveliso ye-silicon esisiseko.

I-Monocrystalline Silicoline solar yegadi

I-Monocrystalline Silicon yindlela ye-silicon yesilivere. Xa isilika esinyibilikisi esiqinileyo someleza, iiathom ze-silicon zilungiselelwa kwi-Wiamond Lagece kwi-nuclei ezininzi zekristali. Ukuba ezi kristali zikhula zibe yingqola kunye nendlela efanayo yenqwelomoya, le migqomo iya kudityaniswa ngokuhambelana ne-monocrystalline yesilico.

I-Monocrystalline Silicolline ineepropathi ezibonakalayo ze-quasi-inyibiliki kwaye ineendlela ezibuthathaka zombane, eziyonyuka ngokukhulisa ubushushu obukhulayo. Kwangelo xesha, iMonocrystalline Silicon ikwanokuphumeza okukhulu kombane. I-Ultra-Hught Monocrystalline Silicon yi-intrinsic semicondcuctor. Ukuqhubela phambili kwe-Iltra-Hughtrystal Silicon kungaphuculwa ngokongeza izinto ze-ⅲA (ezinjengeBoron), kunye nohlobo lwe-silicon zisenziwa. Njengokwengeze ukongezwa kwezinto ze-ⅴA (ezinje nge phosphorus okanye i-arsenic) inokuphucula inqanaba lokuphumelela, ukumiswa kwe-N-Chwethe i-silicondcuctor.

PolysiliciconUkukhanya kwelanga

I-Polysilicicon yindlela ye-silicon yesilivere. Xa isilika etyhidiweyo iqinisa phantsi kwemeko ye-Supercooling, Athom e-Silicon ilungiselelwa kwi-nuclei ezininzi zekristali ngendlela ye-himamond lattle. Ukuba ezi zikristali zikhula zibe ziziinkozo ezinamakhasitha ahlukeneyo, le migca idibanisa kwaye icelela i-polysilicicicon. Ihlukile kwi-monocrystalline, esetyenziselwa kwi-elektroniki kunye neeseli zelanga, kwaye ukusuka kwi-Amoricon Silicon, esetyenziselwa izixhobo zefilimu ezincinci kwayeIiseli zelanga ukukhanya kweGadi

Umahluko kunye nonxibelelwano phakathi kwezi zimbini

KwiMonocrystalline, isakhiwo sekristali yekrimstal siyiyunifomu kwaye sinokubonwa ngenkangeleko yangaphandle engaphandle. Kwi-monocrystalline, i-crystal layicet yesampula yonke iyaqhubeka kwaye ayinamda wengqolowa. Iikristali ezinkulu ezinkulu zinqabile kakhulu kwindalo kwaye kunzima ukwenza ilabhoratri (jonga i-recystallization). Ngokwahlukileyo, izikhundla zeathom kwizakhiwo ze-amorphous zithintelwe uku-odola amafutshane.

I-Polycrystalline kunye nePubcrystalline Plasses zibandakanya inani elikhulu leekristali ezincinci okanye i-microcystals. I-Polysililicon yinto eyenziwe ngamakristali amancinci e-silicon. Iiseli ze-polycrystalline zinokuqonda ukuqulunqwa kwefuthe elibonakalayo sephepha. Ibanga le-semiconductor libandakanya i-Polililifico i-Polililicon iguqulwa ibe yi-monocrystalline, imerika exhunyiwe kwi-polsilicicicon iguqulwe ibe yikristali enkulu. I-Monocrystalline silicon isetyenziselwa ukwenza uninzi lwezixhobo ze-silicon ezisekwe kwisilika. I-Polysilicon inokuphumeza i-99.999% icocekile. I-Ultra-Funal Polysilicilicon ikwasetyenziswa kwicandelo le-semicondcuctor, ezinje nge-2 ukuya kwi-3 -imitha ye-Polysilicon Rod. Kumzi-mveliso we-microelectronics, i-polysilicicon inezicelo zombini kwi-macro kunye nezikali ezincinci. Inkqubo yemveliso ye-monocrystalline yesilico i ibandakanya inkqubo ye-ceckorasky, indawo yokunyibilika kunye ne-bridgman.

Umahluko phakathi kwePolysilicon kunye ne-monocrystalline silicon ibonakaliswa ikakhulu kwiipropathi zomzimba. Ngokuphathelele kwiipropathi zoomatshini kunye nombane, iPolysilicon iphantsi kwe-monocrystalline yesilico. I-Polysilicon inokusetyenziswa njengento ebomvu yokutsala i-monocrystalline yesilivere.

1. Ngokwe-ANISTOTROP yePROPRTUTERE, iipropathi ezibonakalayo kunye neepropathi ze-thermal, kucacile kune-monocrystalline

2. Ngokwemihlaba yepropathi yombane, ukuqhubela kombane kwePolycrystalline ibaluleke kakhulu kunolo hlobo lwe-monocrystalline, okanye phantse akukho mbane

I-3, ngokwemisebenzi yemichiza, umahluko phakathi kwezi zimbini zincinci kakhulu, zisebenzisa i-polysilicicon ngaphezulu
