Musiyano uripo pakati pepolysilicon nemonocrystalline silicon

Zvinhu zvesilicon ndizvo zvinhu zviri nyore uye zvakakosha muindasitiri yesemiconductor. Maitiro akaoma ekugadzira cheni yeindasitiri yesemiconductor anofanirawo kutanga nekugadzira zvinhu zvesilicon zviri nyore.

Monocrystalline silicon solar garden light

Monocrystalline silicon imhando ye elemental silicon. Kana elemental silicon yakanyungudutswa ikaoma, maatomu esilicon anorongwa mu diamond lattice kuita ma crystal nuclei akawanda. Kana ma crystal nuclei aya akakura kuita tsanga dzine tarisiro imwechete ye crystal plane, tsanga idzi dzichabatanidzwa pamwe chete kuti dziite monocrystalline silicon.

Monocrystalline silicon ine hunhu hwe quasi-metal uye ine simba remagetsi risina simba, izvo zvinowedzera nekupisa kuri kuwedzera. Panguva imwe chete, monocrystalline silicon inewo semi-electric conductivity yakakosha. Ultra-pure monocrystalline silicon inhengo yemukati me semiconductor. Kufambiswa kwe ultra-pure monocrystalline silicon kunogona kuvandudzwa nekuwedzera trace ⅢA elements (senge boron), uye P-type silicon semiconductor inogona kuumbwa. Zvakadai sekuwedzerwa kwetrace ⅤA elements (senge phosphorus kana arsenic) kunogonawo kuvandudza mwero we conductivity, kuumbwa kweN-type silicon semiconductor.

Polysilicon imhando yesilicon yechinhu. Kana silicon yechinhu chakanyungudutswa ikaoma pasi pemamiriro ekutonhora zvakanyanya, maatomu esilicon anorongwa kuita manuclei akawanda ekristaro muchimiro chedhaimani lattice. Kana manuclei aya ekristaro akakura kuita zviyo zvine kristalo yakasiyana, zviyo izvi zvinobatana uye zvinoumba polysilicon. Zvinosiyana nesilicon yemonocrystalline, inoshandiswa mumagetsi nemasero ezuva, uye nesilicon isina chimiro, inoshandiswa mumidziyo yefirimu rakatetepa uyemwenje webindu remagetsi ezuva

Musiyano nekubatana pakati pezviviri izvi

Mu monocrystalline silicon, chimiro che crystal frame chakafanana uye chinogona kuonekwa nechitarisiko chekunze chakafanana. Mu monocrystalline silicon, crystal lattice yemuenzaniso wese inoramba iripo uye haina miganhu ye grain. Ma crystals makuru madiki haawanzoonekwi uye akaoma kugadzira murabhoritari (ona recrystallization). Kusiyana neizvi, nzvimbo dzemaatomu muzvimiro zvisina chimiro dzakaganhurirwa pakurongeka kwenzvimbo pfupi.

Mapoinzi ePolycrystalline nesubcrystalline ane huwandu hwakawanda hwemakristaro madiki kana ma microcrystals. Polysilicon chinhu chinoumbwa nemakristaro madiki akawanda esilicon. Masero ePolycrystalline anogona kuziva magadzirirwo nechinhu chinoonekwa nesimbi. Magiredhi eSemiconductor anosanganisira polysilicon yesolar grade anoshandurwa kuita monocrystalline silicon, zvichireva kuti makristaro akabatana zvisina kurongeka mupolysilicon anoshandurwa kuita kristaro hombe imwe chete. Monocrystalline silicon inoshandiswa kugadzira michina yakawanda ye silicon-based microelectronic. Polysilicon inogona kuwana 99.9999% kuchena. Polysilicon yakachena zvikuru inoshandiswawo muindasitiri ye semiconductor, senge polysilicon rods dzakareba mamita maviri kusvika matatu. Muindasitiri ye microelectronics, polysilicon ine mashandisirwo pa macro ne micro scales ese. Maitiro ekugadzira monocrystalline silicon anosanganisira Czeckorasky process, zone melting uye Bridgman process.

Musiyano uripo pakati pepolysilicon nesilicon yemonocrystalline unonyanya kuoneka muhunhu hwepanyama. Panyaya yehunhu hwemakanika nemagetsi, polysilicon yakaderera pane monocrystalline silicon. Polysilicon inogona kushandiswa sezvinhu zvekugadzira monocrystalline silicon.

1. Kana tichitaura nezve anisotropy yehunhu hwemakanika, hunhu hwemaziso uye hunhu hwekupisa, hazvinyatsooneki se monocrystalline silicon

2. Panyaya yehunhu hwemagetsi, kufambiswa kwemagetsi kwepolycrystalline silicon hakuna kukosha zvakanyanya pane kwemonocrystalline silicon, kana kutoti hapana kufambiswa kwemagetsi.

3, maererano nebasa remakemikari, musiyano uripo pakati pezviviri izvi mudiki kwazvo, kazhinji polysilicon inoshandiswa zvakanyanya
