Ubuchwepheshe
I-Molecular Beam Epitaxy, noma i-MBE, iyindlela entsha yokukhulisa amafilimu amancane aphezulu amakristalu ezinhlamvu ze-crystal. Ezimweni ze-vacuum ephezulu-ephezulu, ngesitofu sokushisa sifakwe zonke izinhlobo zezinto ezidingekayo futhi zikhiqize umusi, ngokusebenzisa ugongolo olufanele ekuthwebuleni okukodwa ngasikhathi sinye, kungenza ama-molecule noma ama-athomu kuma-crystal anvy wezakhiwo ifilimu elincanyana ekukhuleni "kokukhula" okuphansi.
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.
Ngakho-ke, i-nitrogen ewuketshezi ethangini elingemuva langaphandle lithuthelwa emishini ye-MBE emafini angenalo uthuli ngokusebenza okuphezulu, ukuqina nokuhlanzeka, akukho ukungcola, amahora angama-24 alawulwa yi-ninternation, uhlelo olunjalo lokulawula izinto zokuhamba lungumkhiqizo ofanele.
Ukumadanisa imishini ye-MBE
Kusukela ngo-2005, imishini ye-HL Crysogenic (HL Cryso) ibilokhu ikwenza kahle futhi kuthuthukise lolu hlelo futhi kubambisana nabakhiqizi be-MBE be-MBE. Abakhiqizi bemishini ye-MBE, kufaka phakathi i-DCA, uReber, babe nobudlelwano bokusebenzisana nenkampani yethu. Abakhiqizi bemishini ye-MBE, kufaka phakathi i-DCA noReber, basebenzisana nenani elikhulu lamaphrojekthi.
I-Ribe SA ingumhlinzeki womhlaba oholayo we-molecular beam epitaxy (MBE) imikhiqizo kanye nezinsizakalo ezihlobene nocwaningo lwe-semiconductor kanye nezicelo zezimboni. Idivaysi ye-Riber Mbe ingabeka izingqimba ezincanyana kakhulu zezinto ezisetshenziswayo egumbini elingaphansi, ngokulawulwa okuphezulu kakhulu. Imishini ye-vacuum ye-HL Crysogenic Equipment (HL Cryso) ifakwe i-Riber SA IMIBHALO ENGCWELEKILE yi-Riber 6000 kanti incane kunazo zonke i-compact 21. Kusesimweni esihle futhi kuqashelwa amakhasimende.
I-DCA yi-oxide ehamba phambili emhlabeni. Kusukela ngo-1993, ukuthuthukiswa okuhlelekile kwamasu we-oxidation, ukufudumeza okuyisisekelo kwe-antioxidant kanye nemithombo ye-antioxidant sekwenziwe. Ngalesi sizathu, izindawo eziningi eziholayo eziholayo zikhethe ubuchwepheshe be-DCA Oxide. Izinhlelo zezinhlanganisela ze-semiconductor Mbe zisetshenziswa emhlabeni wonke. I-VJ liquid nitrogen expane yohlelo lwemishini ye-HL Cryrogenic (HL Cryso) kanye nemishini ye-MBE yamamodeli amaningi we-DCA inolwazi olufanayo kumaphrojekthi amaningi, anjengemodeli P600, R450, SGC800 njll.
