Mfushane we-molecular beam epitaxy (MBE)
Ubuchwepheshe be-molecular beam epitaxy (MBE) yathuthukiswa ngawo-1950s ukulungiselela izinto zefilimu emincane ye-semiconductor usebenzisa ubuchwepheshe be-vacuum ukuphuma kwe-vacuum. Ngokuthuthukiswa kwe-Ultra-High High Technology, ukusetshenziswa kwezobuchwepheshe kunwetshwe emkhakheni wesayensi ye-semiconductor.
Isisusa socwaningo lwe-semiconductor desction yisidingo samadivayisi amasha, angathuthukisa ukusebenza kohlelo. Futhi, ubuchwepheshe obusha bezinto ezibonakalayo bungakhiqiza imishini emisha nobuchwepheshe obusha. I-Molecular Beam Epitaxy (MBE) ingubuchwepheshe obuphezulu be-vacuum yesendlalelo se-Epitaxial (ngokuvamile semiconductor) ukukhula. Isebenzisa ukushisa kokushisa kwama-athomu omthombo noma ama-molecule athinta i-Crystal substrate eyodwa. Izici ze-vacuum eziphakeme zenqubo zivumela ukuxhumeka kwe-in-si situ nasekukhuleni kwezinto zokufaka ezinhlamvu ezisanda kukhula ze-semiconductor.
Ubuchwepheshe be-MBE
UBeam Beam Epitaxy wenziwa nge-vacuum ephezulu noma i-vacuum ephezulu (1 x 10-8Imvelo ye-PA). Isici esibaluleke kakhulu se-molecular beam epitaxy yisilinganiso saso esiphansi sesilinganiso, esivame ukuvumela ifilimu ku-Epitaxial likhule ngesilinganiso esingaphansi kwamanani angama-3000 nm ngehora. Izinga eliphansi eliphansi lidinga i-vacuum ephakeme ezanele ukufezekisa izinga elifanayo lokuhlanzeka njengezinye izindlela zokugcina.
Ukuhlangabezana ne-vacuum ephezulu echazwe ngenhla, idivaysi ye-Mbe (iseli yaseKnudsen) inesendlalelo sokupholisa, kanye nemvelo ye-vacuum ephezulu ye-vacuum yokukhula kufanele igcinwe isebenzisa uhlelo lokujikeleza kwe-nitrogen. I-nitrogen ewuketshezi ipholisa izinga lokushisa langaphakathi ledivayisi ku-77 kelvin (-196 ° C). Imvelo yokushisa ephansi ingaphinde inciphise okuqukethwe ukungcola ku-vacuum futhi inikeze izimo ezingcono zokubekwa kwamafilimu amancanyana. Ngakho-ke, uhlelo lokujikeleza oluzinikezele lwe-nitrogen lokupholisa lwe-nitrogen luyadingeka kwimishini ye-MBE ukuhlinzeka ngokuhlinzekwa okuqhubekayo nokuqinile kwe-Itrogen ye-Iquid ye-Iquid.
I-nitrogen nitrogen ukupholisa ukujikeleza uhlelo
I-Vacuum liquid nitrogen ukupholisa uhlelo lokujikeleza lokujikeleza ngokuyinhloko,
● ithangi le-cryogenic
● I-PIPE EKUQALENI NOKUGCINA KWESITOLO SOKUGCWELEKILE KAKHULU / I-VASEUM KAKHULU
● Isihlukanisi esikhethekile sesigaba esikhethekile kanye nepayipi lokuphelelwa yisikhathi sejacket
● Ama-valuum ahlukahlukene we-vactuum jacketed
● Isithiyo segesi-uketshezi
● Isihlungi se-change jacket
● Uhlelo lwe-Versic Vuuum Pump System
● Ukuqothula kanye nokuhlanza uhlelo lokuvuselela kabusha
Inkampani ye-HL Cryogenic Equipment Company iqaphele ukufunwa kwe-MBE liquid nitrogen ukupholisa uhlelo, i-backbone ehleliwe yezobuchwepheshe ukuthuthukisa ngempumelelo uhlelo olukhethekile lwe-MBE luquid nitrogenedUhlelo lwamapayipi, olusetshenziswe kumabhizinisi amaningi, amanyuvesi kanye nezikhungo zocwaningo.
Imishini ye-HL Cryogenic
Imishini ye-HL Cryogenic eyasungulwa ngo-1992 ingumuntu oxhumene ne-Chengdu Holy Cryogenic Equiment Company in China. Imishini ye-HL Crygenic izimisele ekwakhiweni nasekukhiqizweni kwesistimu ephezulu ye-cryogenic insud ye-cryogening kanye nemishini yokusekelwa ehlobene.
