I-Molecular Beam Epitaxy, noma i-MBE, iyindlela entsha yokukhulisa amafilimu amancane aphezulu amakristalu ezinhlamvu ze-crystal. Ezimweni ze-vacuum ephezulu-ephezulu, ngesitofu sokushisa ifakwe zonke izinhlobo zezinto ezidingekayo futhi zikhiqize umusi, ngezimbobo ezakhiwe ngemuva kokushaywa kwe-atomic noma i-molecular lokushisa elifanelekile le-crystal substrate eyodwa, elawula ugongolo olufanele Ukuskena okuphansi ngasikhathi sinye, kungenza ama-molecule noma ama-athomu ezingxenyeni zokuqondanisa zekristalu ukuze zakhe ifilimu elincanyana ekukhuleni "kokukhula".

Ngokusebenza okujwayelekile kwemishini ye-MBE, ubumsulwa obuphezulu, ingcindezi ephansi kanye ne-nitrogen ephansi ye-ultra-turna kudingeka ukuthi ithuthwe ngokuqhubekayo kwigumbi elipholile lemishini. Ngokuvamile, ithangi elinikezela nge-nitrogen ewuketshezi linokucindezela okukhishwe phakathi kuka-0.3mpa ne-0.8mpa.liquid Nitrogen ku -196 ℃ ifakwa kalula kwi-nitrogen ngesikhathi sokuhamba ngepayipi. Lapho nje i-nitrogen ewuketshezi enesilinganiso esinguketshezi egesi esingaba ngu-1: 700 ifakwe epayipini, izothatha inani elikhulu lesikhala se-nitrogen flow futhi linciphise ukugeleza okujwayelekile ekugcineni kwepayipi le-nitrogen eliwuketshezi. Ngaphezu kwalokho, ethangini lesitoreji se-nitrogen eliwuketshezi, kungenzeka kube yimfucumfucu engahlanzwa. Ku-liquid nitrogen pipeline, ukuba khona komoya omanzi kuzoholela esizukulwaneni seqhwa. Uma lokhu kungcola kukhishwa kwimishini, kuzodala umonakalo ongalindelekile kwimishini.

Therefore, the liquid nitrogen in the outdoor storage tank is transported to the MBE equipment in the dust-free workshop with high efficiency, stability and clean, and the low pressure, no nitrogen, no impurities, 24 hours uninterrupted, such transportation control system is umkhiqizo ofanelekile.
