Kev loj hlob ntawm compound semiconductor crystals
Compound semiconductor hu ua lub cim thib ob ntawm cov khoom siv semiconductor, piv nrog thawj tiam ntawm cov khoom siv semiconductor, nrog kev hloov kho qhov muag, siab electron saturation drift rate thiab kub tsis kam, hluav taws xob tsis kam thiab lwm yam ntxwv, nyob rau hauv ultra-siab ceev, ultra-siab. zaus, tsis tshua muaj zog, tsis tshua muaj suab nrov ntau txhiab thiab circuits, tshwj xeeb tshaj yog cov khoom siv optoelectronic thiab photoelectric cia muaj qhov tshwj xeeb zoo, feem ntau tus neeg sawv cev yog GaAs thiab InP.
Kev loj hlob ntawm cov khoom siv semiconductor ib leeg muaju (xws li GaAs, InP, thiab lwm yam) yuav tsum muaj qhov chaw nruj heev, suav nrog qhov kub thiab txias, cov khoom siv raw purity thiab kev loj hlob purity.PBN tam sim no yog lub nkoj zoo tshaj plaws rau kev loj hlob ntawm cov khoom siv semiconductor ib leeg muaju.Tam sim no, lub compound semiconductor ib leeg siv lead ua txoj kev loj hlob feem ntau suav nrog kua foob ncaj qha rub txoj kev (LEC) thiab ntsug gradient solidification txoj kev (VGF), sib raug rau Boyu VGF thiab LEC series crucible khoom.
Nyob rau hauv cov txheej txheem ntawm polycrystalline synthesis, lub thawv uas siv los tuav lub hauv paus gallium yuav tsum tsis txhob deformation thiab tawg ntawm qhov kub thiab txias, yuav tsum tau siab purity ntawm lub thawv, tsis muaj kev qhia txog impurities, thiab kev pab lub neej ntev.PBN tuaj yeem ua tau raws li tag nrho cov kev xav tau saum toj no thiab yog cov tshuaj tiv thaiv zoo tshaj plaws rau polycrystalline synthesis.Boyu PBN nkoj series tau siv dav hauv cov thev naus laus zis no.
