Fa'apuupuuga o le Molecular Beam Epitaxy (MBE)
O le tekonolosi o le Molecular Beam Epitaxy (MBE) na atiaʻe i le 1950s e saunia ai semiconductor mea manifinifi ata e faʻaaoga ai tekinolosi faʻamalo. Faʻatasi ai ma le atinaʻeina o tekonolosi faʻavavevave ultra-maualuga, o le faʻaogaina o tekinolosi ua faʻalauteleina i le matata o le semiconductor science.
O le faʻaosofiaga o suʻesuʻega mea semiconductor o le manaʻoga mo masini fou, lea e ono faʻaleleia ai le faʻatinoga o le faiga. I le isi itu, o mea fou faatekinolosi e mafai ona maua ai masini fou ma tekinolosi fou. Molecular beam epitaxy (MBE) o se masini masini masini maualuga mo le epitaxial layer (masani semiconductor) tuputupu aʻe. E fa'aogaina le afi vevela o puna'aamu po'o mole mole o lo'o a'afia ai se mea tioata tasi. O uiga gaogao ultra-maualuga o le faagasologa e mafai ai i totonu-situ metallization ma le tuputupu ae o mea insulating i luga o luga o semiconductor fou faatoa tupu, e mafua ai le filogia-saoloto fesootaiga.
MBE Tekonolosi
O le molecular beam epitaxy sa fa'atinoina i se vacuum maualuga po'o le ultra-high vacuum (1 x 10-8Pa) siosiomaga. O le itu pito sili ona taua o le molecular beam epitaxy o lona maualalo o le faʻapipiʻiina, lea e masani ona mafai ai e le ata tifaga ona tupu le epitaxial i se fua faatatau e itiiti ifo i le 3000 nm i le itula. O ia tulaga maualalo e mana'omia ai le maualuga o le vacuum e ausia ai le tulaga tutusa o le mama e pei o isi auala e teu ai.
Ina ia faʻafeiloaʻi le maualuga maualuga o le gaogao o loʻo faʻamatalaina i luga, o le MBE masini （Knudsen cell） o loʻo i ai se vaega malulu, ma le maualuga maualuga o le vacuum siʻosiʻomaga o le potu tuputupu aʻe e tatau ona tausia e faʻaaoga ai le faʻaogaina o le faʻaogaina o le eletise. O le vai e fa'amalieina ai le vevela i totonu o le masini i le 77 Kelvin (−196 °C). O le siosiomaga maualalo o le vevela e mafai ona faʻaititia atili ai mea o le mama i totonu o le vacuum ma maua ai tulaga sili atu mo le tuʻuina o ata manifinifi. O le mea lea, e mana'omia se fa'amalo fa'amalo fa'amalieina o le sua vai mo masini MBE e tu'uina atu ai le fa'aauau pea ma le tumau o le -196 °C vai.
Liquid Nitrogen Cooling Circulation System
Vacuum liquid nitrogen cooling circulation system e masani ona aofia ai,
● tane cryogenic
● fa'alava fa'apalapala fa'aulu ma paranesi paipa / fa'agae'e fa'alava
● MBE vaega fa'apitoa separator ma vacuum jacketed exhaust paipa
● vacuum jacketed valve eseese
● pa puipui kasa-suavai
● faamama peleue mama
● faiga pamu gaogao malosi
● Fa'amalo ma fa'amama ma fa'amama le fa'avevela
HL Cryogenic Equipment Company ua matauina le manaoga o le MBE sua nitrogen faiga malulu, faatulagaina ivi faʻapitoa faʻapitoa e faʻatupuina manuia se MBE faʻapipiʻi faʻapipiʻi faʻapipiʻi faʻapitoa mo tekinolosi MBE ma se seti atoatoa o le vacuum insulate.edfaiga paipa, lea ua faaaogaina i le tele o pisinisi, iunivesite ma suesuega inisitituti.
HL Cryogenic Meafaigaluega
HL Cryogenic Equipment lea na faavaeina i le 1992 o se faʻailoga e fesoʻotaʻi ma Chengdu Holy Cryogenic Equipment Company i Saina. HL Cryogenic Equipment o loʻo tuʻuina atu i le mamanu ma le gaosiga o le High Vacuum Insulated Cryogenic Piping System ma isi mea e fesoʻotaʻi ai.
