Pfupiso yeMolecular Beam Epitaxy (MBE)
Tekinoroji yeMolecular Beam Epitaxy (MBE) yakagadzirwa muma1950 kugadzira zvinhu zve semiconductor thin film uchishandisa tekinoroji ye vacuum evaporation. Nekuvandudzwa kwetekinoroji ye vacuum yakanyanya, kushandiswa kwetekinoroji kwakawedzerwa kumunda wesainzi ye semiconductor.
Chinonyanya kukosha pakutsvagurudza zvinhu zve semiconductor ndechekuti vanoda michina mitsva, izvo zvinogona kuvandudza mashandiro esystem. Nekudaro, tekinoroji itsva yezvinhu zvinogona kugadzira michina mitsva uye tekinoroji itsva. Molecular beam epitaxy (MBE) inyanzvi ye vacuum yakakura yekukura kwe epitaxial layer (kazhinji semiconductor). Inoshandisa kupisa kwemaatomu kana mamorekuru anokanganisa substrate imwe chete yekristaro. Hunhu hwe vacuum hwakakwira zvakanyanya hwemaitiro aya hunobvumira metallization iri munzvimbo uye kukura kwezvinhu zvinodzivirira pazvitsuwa zve semiconductor zvitsva, zvichikonzera ma interfaces asina kusvibiswa.
Tekinoroji yeMBE
Molecular beam epitaxy yakaitwa mu vacuum yakakwira kana kuti ultra-high vacuum (1 x 10).-8Pa) nharaunda. Chinhu chinonyanya kukosha pakukura kwemasero epitaxy ndiko kuderera kwehuwandu hwema "deposition rate", izvo zvinowanzo bvumira firimu kukura nechiyero chisingasviki 3000 nm paawa. Kukura kwehuwandu hwakaderera kudaro kunoda vacuum yakakwana kuti iwane hutsanana hwakafanana nedzimwe nzira dzekubvisa.
Kuti isanganiswe ne vacuum yakanyanya kukwira yakatsanangurwa pamusoro apa, mudziyo weMBE （Knudsen cell）une nzvimbo inotonhorera, uye nzvimbo inotonhorera yakanyanya kukwira yekamuri rekukura inofanira kuchengetedzwa uchishandisa sisitimu yekutenderera kwenitrogen yemvura. Nitrogen yemvura inotonhodza tembiricha yemukati memudziyo kusvika pa77 Kelvin (−196 °C). Nzvimbo inotonhorera yakaderera inogona kuderedza huwandu hwetsvina mu vacuum uye kupa mamiriro ari nani ekuiswa kwemafirimu matete. Nokudaro, sisitimu yekutenderera inotonhorera yemvura yemvura yenitrogen inodiwa kuti michina yeMBE ipe huwandu hunogara huripo hwe -196 °C nitrogen yemvura.
Sisitimu Yekutonhodza Nitrogen Yemvura
Sisitimu yekutonhora yekutenderera kwemvura yeVacuum liquid nitrogen inosanganisira,
● tangi re cryogenic
● pombi huru neyamapazi ine jekete re vacuum / pombi ine jekete re vacuum
● MBE special phase separator uye vacuum jacketed exhaust pipe
● mavharuvhu akasiyana-siyana ane jekete re vacuum
● chipingamupinyi chegasi nemvura
● firita ine jekete remuchina wekuchenesa
● simba rinopisa pombi yepombi
● Kutonhodza uye kuchenesa sisitimu yekudziyisa
Kambani yeHL Cryogenic Equipment yakaona kudiwa kwe MBE liquid nitrogen cooling system, yakaronga technical backbone kuti ibudirire kugadzira MBE liquid nitrogen cooing system yakakosha ye MBE tekinoroji uye seti yakazara ye vacuum insulat.edsisitimu yepombi, iyo yakashandiswa mumakambani mazhinji, mayunivhesiti nemasangano ekutsvagisa.
Midziyo yeHL Cryogenic
Kambani yeHL Cryogenic Equipment yakavambwa muna 1992 ikambani yakabatana neChengdu Holy Cryogenic Equipment Company muChina. HL Cryogenic Equipment yakazvipira mukugadzira nekugadzira High Vacuum Insulated Cryogenic Piping System pamwe nemidziyo yekutsigira yakabatana nayo.
