Nchịkọta nke Molekụla Beam Epitaxy (MBE)
E mepụtara teknụzụ nke Molecular Beam Epitaxy (MBE) n'afọ 1950 iji kwadebe ihe nkiri semiconductor dị gịrịgịrị site na iji teknụzụ vacuum evaporation. Site na mmepe nke teknụzụ vacuum dị elu, itinye teknụzụ n'ọrụ agbasaala na ngalaba sayensị semiconductor.
Ihe na-akpali nnyocha ihe semiconductor bụ ọchịchọ maka ngwaọrụ ọhụrụ, nke nwere ike ime ka arụmọrụ nke sistemụ ahụ ka mma. N'aka nke ya, teknụzụ ihe ọhụrụ nwere ike imepụta akụrụngwa ọhụrụ na teknụzụ ọhụrụ. Molecular beam epitaxy (MBE) bụ teknụzụ vacuum dị elu maka uto oyi akwa epitaxial (nke na-abụkarị semiconductor). Ọ na-eji ọkụ nke atọm isi iyi ma ọ bụ molekul ndị na-emetụta otu kristal substrate. Njirimara vacuum dị elu nke usoro ahụ na-enye ohere ka metallization na uto nke ihe mkpuchi na elu semiconductor etolitere ọhụrụ, na-ebute njikọ na-enweghị mmetọ.
Teknụzụ MBE
A na-eme epitaxy nke molekul beam n'ime oghere dị elu ma ọ bụ oghere dị elu (1 x 10-8Pa) gburugburu ebe obibi. Ihe kachasị mkpa nke epitaxy nke molekul bụ obere ọnụego ya, nke na-enyekarị ohere ka ihe nkiri ahụ too na ọnụego na-erughị 3000 nm kwa elekere. Ọnụego obere ntinye dị otú ahụ chọrọ nnukwu oghere iji nweta otu ọkwa nke ịdị ọcha dịka ụzọ ntinye ndị ọzọ.
Iji mezuo oghere dị oke elu nke akọwara n'elu, ngwaọrụ MBE (Knudsen cell) nwere oyi akwa oyi, a ga-ejikwa sistemụ mgbasa nitrogen mmiri mmiri nọgide na-enwe oghere dị oke elu nke oghere uto. Nitrogen mmiri mmiri na-eme ka okpomọkụ dị n'ime ngwaọrụ ahụ dị jụụ ruo 77 Kelvin (−196 °C). Gburugburu okpomọkụ dị ala nwere ike ibelata ọdịnaya nke ihe ndị na-adịghị ọcha na oghere ma nye ọnọdụ ka mma maka itinye ihe nkiri dị gịrịgịrị. Ya mere, a chọrọ sistemụ mgbasa nitrogen mmiri mmiri raara onwe ya nye maka akụrụngwa MBE iji nye nitrogen mmiri -196 °C na-aga n'ihu ma na-adịgide adịgide.
Sistemụ Mgbasa Oyi nke Nitrogen Mmiri
Sistemụ mgbasa mmiri mmiri ikuku nitrogen jụrụ oyi gụnyere,
● tankị mmiri ozuzo
● ọkpọkọ jaketị isi na alaka / hose jaketị vacuum nke a kpụrụ akpụ na isi na alaka
● MBE pụrụ iche nkewa na ọkpọkọ ikuku a na-eji ihe mkpuchi eme ihe
● valvụ dị iche iche e ji ihe mkpuchi valvụ mee
● ihe mgbochi mmiri mmiri gas
● ihe nzacha a na-eji ihe mkpofu eme
● sistemụ mgbapụta ikuku ike
● Sistemụ ikpo ọkụ ọhụrụ tupu oge oyi na nhicha
Ụlọ ọrụ HL Cryogenic Equipment Company ahụla mkpa nke sistemụ oyi mmiri mmiri MBE, ha haziri ntọala teknụzụ iji mepụta sistemụ mkpuchi mmiri mmiri MBE pụrụ iche maka teknụzụ MBE na ihe mkpuchi ikuku zuru oke.edsistemụ ọkpọkọ, nke ejirila mee ihe n'ọtụtụ ụlọ ọrụ, mahadum na ụlọ ọrụ nyocha.
