Luv luv ntawm molecular nqaj epitaxy (MBE)
Tshuab thev naus laus zis molecular nqaj epitaxy (MBE) tau tsim nyob rau xyoo 1950 los npaj cov ntaub ntawv zaj duab xis nyias nyias siv lub tshuab nqus hluav taws xob. Nrog rau kev txhim kho ntawm ultra-siab nqus thev naus laus zis, daim ntawv thov kev thev naus laus zis tau txuas ntxiv mus rau tom teb ntawm semiconductor science.
Qhov kev txhawb siab ntawm cov ntaub ntawv tshawb fawb semiconduct yog qhov kev thov rau cov khoom siv tshiab, uas yuav txhim kho kev ua haujlwm ntawm lub system. Hauv lem, cov khoom siv tshiab thev naus laus zis yuav tsim cov cuab yeej tshiab thiab thev naus laus zis. Molecular nqaj Epitaxy (MBE) yog lub siab nqus tshuab rau cov txheej kab ntawv kab mob ecitaxial (feem ntau semiconductor) kev loj hlob. Nws siv cov nqaj kub ntawm cov peev txheej atoms lossis lwg me me cuam tshuam tib lub tshuab siv lead ua substrate. Lub tshuab hluav taws xob ultra-siab ntawm cov txheej txheem tso cai rau hauv-sithozation thiab kev loj hlob ntawm insulating cov ntaub ntawv ntawm cov neeg muaj kuab paug, ua rau muaj kuab paug-interfaces.
MBE Technology
Cov molecular nqaj epitaxy tau nqa tawm hauv lub tshuab nqus tsev siab los yog ultra-siab nqus (1 x 10-8PA) ib puag ncig. Qhov tseem ceeb tshaj plaws ntawm molecular nqaj xaiv tus nqi, uas feem ntau tso cai rau cov yeeb yaj kiab rau qhov tsawg dua 3000 toj ib teev. Xws li tus nqi tso nyiaj qis qis yuav tsum tau lub tshuab nqus tsev kom muaj zog kom ua tiav tib theem ntawm kev nyiam huv si li lwm txoj kev tso nyiaj.
Txhawm rau ntsib Ultra-siab lub tshuab nqus tsev tau piav qhia saum toj no, MBE cov cuab yeej tau piav qhia saum toj no, MBE txheej (Knudsen cell) muaj kev loj hlob ntawm cov pa roj coord Ua kua nitrogen txias lub cuab yeej sab hauv kub mus rau 77 kelvin (-196 ° C). Qhov chaw ntsuas kub tsawg tuaj yeem txo cov ntsiab lus ntawm kev tsis txaus siab nyob rau hauv nqus tsev thiab muab cov xwm txheej zoo dua rau cov yeeb yaj kiab nyias. Yog li ntawd, ib qho kev ua kua dej siab rau cov txheej txheem rau cov khoom siv
Ua kua nitrogen txias ncig
Nqus dej ua kua nitrogen txias ncig kev cai feem ntau suav nrog,
● Cryogenic Tank
● Cov tshuab nqus tsev loj thiab txhais khaus jackhawm / lub tshuab nqus tsev Jose
● MBE TSHWJ XEEB SEPARATOR THIAB LUB TSHUAB NQUS PLAV JASTEDED YEEB NKAB
● Ntau lub tshuab nqus tsev tau txais li qub
● Roj-Ua Kua Teeb Meem
App Lub puab tsaig Jacketed lim
Lub tshuab nqus tsev nrawm nrawm system
● Ua ntej mus thiab ntxuav cov txheej txheem rheathing
Hl cryogenic cov cuab yeej siv tau pom qhov kev thov ua kua nitrogen txias system rau mbe technology thiab ua tiav txheej txheej ntawm lub tshuab nqus tsevedCov kab ke nkag, uas tau siv nyob rau hauv ntau cov lag luam, cov tsev kawm qib siab thiab cov chaw tshawb fawb.
Hl cryogenic khoom
Ua cov khoom siv cryogenic uas tau tsim nyob rau xyoo 1992 yog ib hom neeg koom rau Chengdu Cov Khoom Siv Cryogenic Khoom Siv Hauv Suav teb. Siv cov khoom siv cryogenic tau cog lus rau cov qauv tsim thiab tsim cov tshuab nqus tsev siab insulated cryogenic piping system thiab cuam tshuam cov cuab yeej siv.
