Pfupiso yeMolecular Beam Epitaxy (MBE)
Tekinoroji yeMolecular Beam Epitaxy (MBE) yakagadziridzwa mu1950s kugadzirira semiconductor yakatetepa firimu zvinhu uchishandisa vacuum evaporation tekinoroji. Nekuvandudzwa kweyepamusoro-soro vacuum tekinoroji, kushandiswa kwetekinoroji kwakawedzerwa kumunda wesainzi semiconductor.
Iko kukurudzira kwe semiconductor zvinhu zvekutsvaga ndiko kudiwa kwemidziyo mitsva, iyo inogona kuvandudza mashandiro ehurongwa. Nekudaro, tekinoroji nyowani inogona kugadzira michina mitsva uye tekinoroji nyowani. Molecular beam epitaxy (MBE) tekinoroji yepamusoro yekuvharisa epitaxial layer (kazhinji semiconductor) kukura. Iyo inoshandisa kupisa danda reatomu sosi kana mamorekuru anokanganisa imwechete crystal substrate. Iwo ekupedzisira-akakwira vacuum maitiro eiyo maitiro anobvumira in-situ simbi uye kukura kwezvinhu zvinodzivirira pazvichangobva kukura semiconductor nzvimbo, zvichikonzera kusvibiswa-isina nzvimbo.
MBE Technology
Iyo molecular beam epitaxy yakaitwa mune yakakwira vacuum kana Ultra-yakakwira vacuum (1 x 10).-8Pa) nharaunda. Iyo inonyanya kukosha yemolecular beam epitaxy ndiyo yakaderera deposition rate, iyo inowanzobvumira iyo firimu kuti epitaxial ikure pamwero wepasi pe3000 nm paawa. Iyo yakaderera deposition rate inoda yakakwira yakakwana vacuum kuti iwane nhanho imwechete yehutsanana sedzimwe nzira dzekuisa.
Kuti usangane ne-ultra-high vacuum inotsanangurwa pamusoro, iyo MBE mudziyo (Knudsen cell) ine inotonhorera layer, uye yakanyanya-yakakwirira vacuum nharaunda yekamuri yekukura inofanira kuchengetedzwa uchishandisa mvura nitrogen circulation system. Liquid nitrogen inotonhodza tembiricha yemukati yemudziyo kusvika pa77 Kelvin (−196 °C). Iyo yakaderera tembiricha nharaunda inogona kuwedzera kudzikisa zviri mukati metsvina muvacuum uye inopa zvirinani mamiriro ekuiswa kwemafirimu matete. Naizvozvo, yakatsaurirwa mvura nitrogen inotonhorera kutenderera system inodiwa kuti MBE midziyo ipe inoenderera uye yakatsiga kupihwa kwe -196 °C mvura yenitrogen.
Liquid Nitrogen Kutonhora Kutenderera System
Vacuum liquid nitrogen inotonhorera kutenderera system inonyanya kusanganisira,
● cryogenic tank
● huru uye bazi vacuum jacketed pombi / vacuum jacketed hose
● MBE yakakosha nhanho separator uye vacuum jacketed kubudisa pombi
● siyana vacuum jacketed mavharuvhu
● gasi-mvura inodzivirira
● vacuum jacketed sefa
● dynamic vacuum pump system
● Precooling uye kuchenesa reheating system
HL Cryogenic Equipment Company yakaona kudiwa kweMBE liquid nitrogen kutonhora system, yakaronga tekinoroji musana kuti ubudirire kugadzira yakakosha MBE liquid nitrogen cooing system yeMBE tekinoroji uye seti yakazara yevacuum insulat.edpiping system, iyo yakashandiswa mumabhizinesi mazhinji, mayunivhesiti uye masangano ekutsvagisa.
HL Cryogenic Equipment
HL Cryogenic Equipment iyo yakavambwa muna 1992 imhando yakabatana neChengdu Holy Cryogenic Equipment Company kuChina. HL Cryogenic Equipment yakazvipira dhizaini nekugadzira iyo Yepamusoro Vacuum Insulated Cryogenic Piping System uye yakabatana Tsigiro Equipment.
