Molecular nqaj epitaxy (MBE) yog cov kws qhia nyias muaj siv los ua cov duab nyias nyias thiab nanostructures rau ntau yam kev siv, Optoelectronics, thiab Quantum suav. Ib qho ntawm cov kev sib tw tseem ceeb hauv MBE lub tshuab yog tswj cov kub tsis tshua muaj kub, uas yog qhov twgLub Tshuab Nqus Tsev Jacketiged Yeeb Nkabs (vjp) tuaj rau hauv kev ua si. Cov kav dej siab yog qhov tseem ceeb rau kev tswj cov thermal hauv Mbe Chambers hauv kev ua tiav cov ntaub ntawv zoo ntawm cov ntaub ntawv ntawm qib atomic.
Dab tsi yog molecular nqaj epitaxy (MBE)?
MBE yog cov txheej txheem tso tawm ntawm cov koom nrog cov kev tswj hwm ntawm atomic lossis molecular nqaj mus rau ib puag ncig lub siab. Cov txheej txheem yuav tsum tau ua kom sov siab kom ua tiav cov khoom xav tau, uas ua rau cov kev tswj hwm thermal tseem ceeb. Hauv MBE lub nruab nrab,Lub tsev txhij cov kav dejtau siv los nqa cov kua roj thiab roj av, kom meej tias cov substrate tseem nyob ntawm qhov ntsuas kub nyob rau ntawm qhov ntsuas kub.
Lub luag haujlwm ntawm lub tshuab nqus tsev Jackinged kav hauv MBE cov tshuab
Hauv MBe thev naus laus zis,Lub tsev txhij cov kav dejFeem ntau siv los thauj cryogens xws li ua kua nitrogen thiab cov kua helium kom txias lub pas dej mbe thiab cuam tshuam. Cov kav dej muaj cov yeeb nkab sab hauv uas tuav cov kua cryogenic, puag ncig los ntawm cov tsho sab nraud nrog lub tshuab nqus tsev. Lub tshuab nqus tsev hluav taws xob tsis zoo, tiv thaiv kev tiv thaiv kev hloov pauv thiab ua kom cov txheej txheem hnyav uas xav tau rau MBE.
Qhov zoo ntawm kev siv lub tshuab nqus tsev jackinged kav hauv MBE thev naus laus zis
Kev sivLub tsev txhij cov kav dejHauv MBE thev naus laus zis muaj ob peb zoo. Ua ntej, lawv paub tseeb tias cov thermal tswj yuav tsum rau cov zaj duab xis tso tseg, uas yog qhov tseem ceeb rau kev ua tiav cov khoom siv sib txawv ntawm kev ua tiav cov khoom siv sib txawv. Thib ob, lawv pab txo qis kev pheej hmoo ntawm kev paug hauv MBE ib puag ncig los ntawm kev saib xyuas kev ncaj ncees ntawm lub tshuab nqus tsev. Thaum kawg,Lub tsev txhij cov kav dejTxhim kho qhov ua tau zoo tag nrho ntawm Mbe system los ntawm kev txo qis cov rwj-tawm ntawm cov roj cryogenic, ua rau cov nqi qis dua thiab siv sijhawm ua haujlwm ntev dua.
Lub neej yav tom ntej ntawm lub tshuab nqus tsev jewinged kav hauv MBE cov ntawv thov
Raws li Mbe Technology txuas ntxiv hloov zuj zus thiab xav tau kom muaj nuj nqis siab dua,Lub tsev txhij cov kav dejyuav ua lub luag haujlwm tseem ceeb ntxiv. Kev nrhav hauv cov ntaub ntawv rwb thaiv tsev thiab kev tsim qauv ntawm cov kav dej, txhim kho lub zog hluav taws xob ntawm Mbe Systems thiab ua kom cov khoom siv ntawm cov ntaub ntawv ntau dua. Raws li kev lag luam zoo li semiconductor raug thiab quantum suav txuas ntxiv mus nthuav tawm, qhov xav tau kev tswj hwm kev txhim khu kev qha thiab ua kom muajLub tsev txhij cov kav dej, yuav tsuas loj hlob.
Hauv kev xaus,Lub tsev txhij cov kav dejYog cov khoom tseem ceeb hauv MBE cov txheej txheem, ua kom cov kev tswj kom sov kub thiab kub ua kom tiav cov yeeb yaj kiab zoo. Raws li qhov kev thov rau cov ntaub ntawv tshaj lij ntxiv, cov kav dej no yuav nyob tseem ceeb rau kev tswj hwm qhov chaw tsawg-ib puag ncig thev naus laus zis.
