Lisebelisoa tsa silicon ke lisebelisoa tsa mantlha le tsa mantlha indastering ea semiconductor.Ts'ebetso e rarahaneng ea tlhahiso ea ketane ea indasteri ea semiconductor le eona e lokela ho qala ho tsoa tlhahiso ea thepa ea motheo ea silicon.
Leseli la serapa sa letsatsi la Monocrystalline silicon
Monocrystalline silicon ke mofuta oa silicon ea motheo.Ha silicon ea motheo e qhibilihisitsoeng e tiea, liathomo tsa silicon li hlophisitsoe ka lesela la daemane ka har'a li-nuclei tse ngata tsa kristale.Haeba li-nuclei tsena tsa kristale li hola ho ba lijo-thollo tse nang le sebopeho se ts'oanang sa sefofane sa kristale, lithollo tsena li tla kopanngoa ka ho bapisa ho benya ka silicon ea monocrystalline.
Monocrystalline silicon e na le thepa ea 'mele ea quasi-metal mme e na le conductivity e fokolang ea motlakase, e ntseng e eketseha ka mocheso o ntseng o eketseha.Ka nako e ts'oanang, silicon ea monocrystalline e boetse e na le conductivity ea bohlokoa ea semi-electrical conductivity.Silicon ea Ultra-pure monocrystalline ke semiconductor ea kahare.The conductivity ea ultra-pure monocrystal silicon e ka ntlafatsoa ka ho eketsa trace Ⅲ A elements (joaloka boron), le P-type silicon semiconductor e ka thehoa.Joalo ka ho eketsoa ha likarolo tsa trace ⅤA (tse kang phosphorus kapa arsenic) li ka boela tsa ntlafatsa tekanyo ea conductivity, ho thehoa ha N-mofuta oa silicon semiconductor.
Polysilicon ke mofuta oa elemental silicon.Ha silicon ea motheo e qhibilihisitsoeng e tiea tlas'a boemo ba supercooling, liathomo tsa silicon li hlophisitsoe ka har'a li-nuclei tse ngata tsa kristale ka mokhoa oa lesela la daemane.Haeba li-nuclei tsena tsa kristale li hola ho ba lijo-thollo tse nang le chebahalo e fapaneng ea kristale, lithollo tsena lia kopana ebe li phatsima ho ba polysilicon.E fapane le silicon ea monocrystalline, e sebelisoang ho lisebelisoa tsa elektronike le lisele tsa letsatsi, le ho silicon ea amorphous, e sebelisoang lisebelisoa tsa filimi e tšesaane lelisele tsa letsatsi lebone la serapa
Phapang le kamano pakeng tsa tse peli
Ka silicon ea monocrystalline, sebopeho sa foreimi ea kristale se ts'oana 'me se ka khetholloa ka ponahalo e tšoanang ea kantle.Ka silicon ea monocrystalline, lesela la kristale la sampuli eohle le tsoela pele ebile ha le na meeli ea lijo-thollo.Likristale tse kholo tse le 'ngoe li fumaneha seoelo ka tlhaho ebile ho thata ho li etsa ka laboratoring (sheba recrystallization).Ka lehlakoreng le leng, maemo a liathomo meahong ea amorphous a lekanyelitsoe ho tatellano ea nako e khuts'oane.
Likarolo tsa polycrystalline le subcrystalline li na le palo e kholo ea likristale tse nyane kapa li-microcrystals.Polysilicon ke thepa e entsoeng ka likristale tse ngata tse nyane tsa silicon.Lisele tsa polycrystalline li ka lemoha sebopeho ka phello e bonahalang ea tšepe.Limaraka tsa semiconductor tse kenyelletsang polysilicon ea solar grade li fetoloa silicon ea monocrystalline, ho bolelang hore likristale tse kopantsoeng ka mokhoa o sa reroang ka polysilicon li fetoloa kristale e kholo e le 'ngoe.Monocrystalline silicon e sebelisoa ho etsa lisebelisoa tse ngata tsa silicon-based microelectronic.Polysilicon e ka fihlela bohloeki ba 99.9999%.Ultra-pure polysilicon e boetse e sebelisoa indastering ea semiconductor, joalo ka 2 - ho 3-meter polysilicon e telele.Indastering ea li-microelectronics, polysilicon e na le ts'ebeliso ho likala tse kholo le tse nyane.Mekhoa ea tlhahiso ea silicon ea monocrystalline e kenyelletsa ts'ebetso ea Czeckorasky, ho qhibiliha ha libaka le ts'ebetso ea Bridgman.
Phapang pakeng tsa polysilicon le monocrystalline silicon e bonahala haholo-holo ka thepa ea 'mele.Mabapi le thepa ea mechine le ea motlakase, polysilicon e ka tlaase ho silicon ea monocrystalline.Polysilicon e ka sebelisoa e le lisebelisoa tse tala bakeng sa ho taka silicon ea monocrystalline.
1. Mabapi le anisotropy ea thepa ea mechine, thepa ea optical le thepa ea mocheso, ha e bonahale haholo ho feta monocrystalline silicon.
2. Mabapi le thepa ea motlakase, motlakase oa silicon ea polycrystalline ha o bohlokoa haholo ho feta oa silicon ea monocrystalline, kapa hoo e batlang e se na motlakase oa motlakase.
3, mabapi le ts'ebetso ea lik'hemik'hale, phapang lipakeng tsa tse peli e nyane haholo, hangata e sebelisa polysilicon ho feta
