Molecular Brem Epitaxy (MBE) ndi njira yodziwika bwino yomwe imagwiritsidwa ntchito popanga mafilimu oonda ndi ma nanitsandalama osiyanasiyana omwe amagwiritsidwa ntchito, kuphatikizapo semiconduction zida, mafilimu, ndi magwiridwe antchito. Chimodzi mwazovuta zazikulu mu mbewu zimasunga kutentha pang'ono, komwe kuliChitoliro cha JambulaniS (VJP) idzayamba kusewera. Mapaipi apamwamba awa ndi ofunikira kuwonetsetsa mankhwala mu zipinda za MBA, ndikuwapangitsa kukhala chinthu chofunikira kwambiri pakukwaniritsa kukula kwakukulu kwa zida zapamwamba pa mulingo wa atomiki.
Kodi molecular yamtundu wa staxy (MBE) ndi chiyani?
MBE ndi njira yoyambira kuwongolera mawonekedwe a atomiki kapena matabwa owoneka bwino m'malo mwake. Njirayi imafuna kuwongolera kutentha kuti mukwaniritse zomwe mukufuna, zomwe zimapangitsa kuwongolera mafuta kukhala chinthu chotsutsa. Mu kachitidwe,Mapaipi a Jambulani Jambulaniamagwiritsidwa ntchito kunyamula zakumwa ndi mpweya wa crobogenic, ndikuwonetsetsa kuti gawo lapansi limatsalira pa kutentha kosayenera panthawi yowoneka bwino.
Udindo wa Mapaipi Opanda Jambum mu MBE
Muukadaulo wa MBE,Mapaipi a Jambulani Jambulanizimagwiritsidwa ntchito makamaka ponyamula ma christoge omwe amadzimadzi ndi madzi a nayitrogeni ndi helium kuti aziziziritsa mbewu la MBE m'chipinda chogwirizana. Mapaipi amakhala ndi chitoliro chamkati chomwe chimakhala ndi ma chrisbogenic madzi, atazunguliridwa ndi jekete lakunja lokhala ndi vuto lokhala ndi mpweya. Kusintha kwa vacuum uyu kumachepetsa kusamutsa kutentha, kupewa kusinthasintha ndikuwonetsetsa kuti kachitidwe kalima kutentha kofunikira kwambiri ku MB.
Ubwino wa Kugwiritsa Ntchito Mapaipi a Jambum Yachikhalidwe mu MBE
Kugwiritsa ntchitoMapaipi a Jambulani JambulaniMu ukadaulo wa MBA umapereka zabwino zambiri. Choyamba, amaonetsetsa kuti matenthedwe amafunikira kuti azikhala ndi mawonekedwe apamwamba kwambiri, omwe ndi ofunikira kuti akwaniritse kukula kwa yufolomu. Chachiwiri, amathandizira kuchepetsa chiopsezo cha kuipitsidwa mu mbele kukhala kusunga kukhulupirika kwa vacuum. Komaliza,Mapaipi a Jambulani JambulaniSinthani mphamvu yonse ya Mbeyo mwa kuchepetsa chithupsa-chotsika cha ma crygenic zakumwa, zomwe zimayambitsa kuchepa kwa ntchito ndi njira yayitali.
Tsogolo la Mapaipi a VBUMOPA TIPA
Monga ukadaulo wa MBE zikupitilirabe ndipo zofuna za kuwongolera kwambiri,Mapaipi a Jambulani Jambulaniadzatenga gawo lofunikira kwambiri. Zovuta muzinthu zokongoletsera ndi mapangidwe zidzakuthandizaninso magwiridwe ake a upaipi awa, kumawonjezera mphamvu yamagetsi ya MBE ndikuthandizira kuphatikizika kwa zida zapamwamba kwambiri. Monga mafakitale monga semiconducki yopanga ndi kuchuluka kwa ndalama zikupitilirabe, kufunikira kodalirika komanso kotheratu koyenera, mongaMapaipi a Jambulani Jambulani, imangokula.
Pomaliza,Mapaipi a Jambulani Jambulanindi gawo lofunikira mu MBE, kupangitsa kutentha kwa kutentha ndikuonetsetsa kuti zinthu zikuyenda bwino kwambiri. Monga kufunikira kwa zinthu zapamwamba kukupitilizabe, ziphuphu izi zikhala zofunikira kuti zizikhala zotsika mtengo kwambiri zimafunikira ukadaulo wa MB.
