Kev Tshaj Tawm Txheej Txheej Raug Tawm Tau Peb Hom

Evaporation txheej qhov chawmuajpeb hom.
(1) ua haujlwm tiv thaiv cua sov qhov chaw: nrog cov hlau refractory xws li tungsten, tantalum ua los ntawm cov ntawv ci lossis filamate, dhau ntawm qhov tam sim no, cua sov hauv qhov saum toj nws lossis muab tso rau hauv cov khoom siv ua kom tau zoo evaporating, cov khoom ua kom muaj cua sov yog siv rau cov evaporation ntawm Cd, Pb , Ag, Al, Cu, Cr, Au, Ni thiab lwm yam ntaub ntawv;
(2) high zaus induction cua sov qhov chaw: siab loj induction tam sim no cua sov crucible thiab evaporating yam;
(3)Cov hluav taws xob nqaj cua sov qhov chaw: tsim nyog rau cov tshuab hluav taws xob kub siab (tsis pub tsawg dua 2000 [618-1]) ntawm cov khoom, uas yog, cov khoom siv hluav taws xob cov nplaim hluav taws xob ua kom nws nqus tau.
Piv nrog rau lwm cov txheej txheej nqus tsev, txheej txheej evaporative muaj qhov kev tso nyiaj ntau dua thiab tuaj yeem siv los npaj cov yeeb yaj kiab ua ke nrog cov khoom ua kom muaj zog thiab nyuaj nyuaj kev ua kom sov.
Yuav kom tso nyiaj siab huv tib leeg siv lead ua cov yeeb yaj kiab, siv molecular beam epitaxy tuaj yeem siv. Cov khoom siv molecular nqaj epitaxy ntawm kev loj hlob-doped GaAlAs ib leeg siv lead ua txheej. Cov dav hlau cua sov yog nruab nrog lub qhov taw qhia molecular. Thaum nws tau rhuab mus rau qee qhov kub hauv qhov nruab nrab ultra-siab nqus, cov khoom hauv lub tshuab ua kom sov tua mus rau qhov tsis txaus hauv qhov dej molecular. Thaum lub substrate yog rhuab mus rau ib qho kub, cov lwg me me tso rau ntawm lub substrate tuaj yeem txav chaw thiab loj hlob muaju raws li cov lattice xaj ntawm lub substrate. High purity compound ib siv lead ua cov yeeb yaj kiab nrog cov yam ntxwv ntawm cov txheej txheem stoichiometric tuaj yeem tau los ntawm kev siv molecular beam epitaxy qauv. Kev loj hlob qeeb kawg ntawm zaj duab xis tuaj yeem tswj tau ntawm 1 monolayer / thib ob. Los ntawm kev tswj hwm tus baffle, qhov tsim nyog xav tau thiab cov qauv ntawm ib daim nyias nyias nyias zaj duab xis tuaj yeem ua tau. Molecular beam epitaxy yog siv dav hauv cov khoom tsim ntawm ntau yam khoom siv sib txuam nrog cov thev naus laus zis thiab superlattice qauv zaj duab xis

IKS PVD tuam txhab, lub tshuab ua kom zoo nkauj, cuab yeej txheej tshuab, kho qhov muag txheej tshuab, PVD nqus plua plav txheej kab, qhov phiaj xwm ua haujlwm tseem ceeb muaj. Ua rau peb tam sim no, E-mail: {{2}
