Ubuchwepheshe be-Molecular Beam Epitaxy bathuthukiswa yi-Bell Laboratories ekuqaleni kwawo-1970 ngesisekelo sendlela yokubeka i-vacuum kanye nesifundo sika-Arthur mayelana ne-reaction kinetics ye-gallium njengokuxhumana kwe-athomu ne-GaAs surface ngo-1968. Bukhuthaza ukuthuthukiswa kwesizukulwane esisha sesayensi ye-semiconductor kanye nobuchwepheshe obusekelwe ezintweni zokwakha ezincane ezingqimba ezincane kakhulu. I-Molecular beam epitaxy (MBE) ubuchwepheshe befilimu encane eguquguqukayo ye-epitaxy, obungachazwa njengokukhiqiza izinto zefilimu encane ezisezingeni eliphezulu noma izakhiwo ezahlukahlukene ezidingekayo ngokubonisa ama-athomu noma imishayo yama-molecule ekhiqizwa ukuhwamuka kokushisa ku-substrate ehlanzekile enesimo esithile kanye nokushisa endaweni ye-vacuum ephezulu kakhulu.
Ukuhlaziywa kosayizi wemakethe yesistimu ye-molecular beam epitaxy (MBE)
Uhlelo lwe-epitaxial lwe-molecular beam luyithuluzi elibalulekile lezinto ezintsha ze-semiconductor kanye ne-photovoltaic kanye nocwaningo lwenqubo. Usayizi wemakethe yomhlaba wonke we-molecular beam epitaxial system ufinyelele ku-USD 81.48 million ngo-2020, futhi kulindeleke ukuthi ufinyelele ku-USD 111 million ngo-2026, ngesilinganiso sokukhula sonyaka esihlanganisiwe (CAGR) esingu-5.26%.
IYurophu njengamanje yindawo enkulu kunazo zonke emhlabeni yokukhiqiza uhlelo oluhlanganisiwe lweqembu, futhi ithunyelwa kwamanye amazwe emazweni amaningi emhlabeni, angeniswa kakhulu ngokungenisa kwamanye amazwe, yize kunenani elincane labakhiqizi abanekhono lokukhiqiza, kodwa umkhiqizo awanelanga futhi udinga ukuthuthukisa ngokushesha inani lomkhiqizo ukuze ubambe imakethe. Ngesikhathi esifanayo, ngokuthuthukiswa kwemboni ye-semiconductor kanye nezinto ezibonakalayo, ikhasimende libeke phambili izidingo zekhwalithi ezengeziwe kanye nezinkomba zobuchwepheshe eziphakeme njengocwaningo oluyinhloko kanye nohlelo lwe-molecular beam epitaxy lwemishini yokukhiqiza, futhi ushintsho ekucacisweni luya ngokuya luhlukahluka. Ibhizinisi le-molecule beam epitaxial system kufanele lithuthukise ngenkuthalo ikhwalithi yomkhiqizo, ngaleyo ndlela lenze imikhiqizo yalo ikhange.
Abakhiqizi abakhulu besistimu ye-molecular coepitaxial emakethe bahlanganisa i-veecoc yaseMelika, i-riber kanye ne-Finland dca, kanti uhlobo oluvamile lwemikhiqizo ye-fastipron yama-molecule luyimikhiqizo eminingi, njenge-veeco, i-riber kanye ne-sienta omicron, njll. Umkhiqizi wesistimu ye-epitaxial ye-laser molecular beam ikakhulukazi uhlanganisa i-Japan pascaly, i-Netherlands TSST, njll. Njengamanje, uhlelo lwe-epitaxial ye-molecular beam epitaxial olujwayelekile luyimakethe yokuthengisa eyinhloko, isabelo semakethe singama-73%, uhlelo lwe-epitaxial ye-laser molecular beam lusetshenziswa kabanzi ngenxa yefilimu efanelekile ukukhula kwe-polyelement, iphuzu lokuncibilika eliphezulu kanye nesakhiwo sengqimba esiyinkimbinkimbi.
Uhlelo lwe-molecular beam epitaxy lusetshenziswa kakhulu ocwaningweni lwezinto ze-semiconductor kanye nezinto eziyisisekelo. Umthengi oyinhloko wohlelo lwe-cluster epitaxy yizwe elinesistimu yezimboni ephelele, njengeYurophu, i-United States, iJapan kanye neChina, okubalwa ngaphezu kwamaphesenti angama-80 emakethe yomhlaba. Ngesikhathi esifanayo, amazwe asathuthuka njenge-India, i-Southeast Asia kanye neminye iminyaka yamuva nawo andise kancane kancane ukutshalwa kwezimali emikhakheni yocwaningo oluyisisekelo, futhi ikusasa lizoba namandla amakhulu emakethe.
Ukusabalala komnotho womhlaba wonke kube ngenxa yentuthuko yomnotho womhlaba kanye ne-semiconductor, okunzima ukuyiqinisekisa emandleni ebhizinisi kanye nemakethe engezansi, okuholele nasekubeni nenkinga ethile ekukhiqizweni kweqembu lama-microexpanses, njengokwehla kokuthengiswa kwenkampani engxenyeni yokuqala yonyaka engxenyeni yokuqala yonyaka, ngakho-ke ibhizinisi lidinga ukugcina ukuhamba kwemali okwanele ukuze libhekane nokuthuthukiswa kokuqubuka kwalesi sifo. Nakuba kunezinkinga zemvelo zangaphandle kanye nokuncintisana kwemboni, sikholelwa ukuthi umbono wemakethe wemboni yamabhange useyithemba elithile lentuthuko, futhi ukutshalwa kwezimali kwemboni kuzoqhubeka nokukhula.
Uhlelo Lokujikeleza Kokupholisa lwe-MBE Liquid Nitrogen
Imishini ye-MBE idinga ukuba phezulu futhi isheshe, ngakho-ke igumbi lidinga ukuphola. I-HL inezinhlobo eziphelele zezixazululo zokujikeleza komoya ezivuthiwe ze-nitrogen ewuketshezi.
Uhlelo lokujikeleza olupholile lwe-nitrogen oluyi-liquid luqukethe amapayipi afakwe i-vacuum insulation (VI), amapayipi aguquguqukayo e-VI, ama-valve e-VI, isihlukanisi sesigaba sokujikeleza se-VI njll.
Imishini ye-HL Cryogenic
I-HL Cryogenic Equipment eyasungulwa ngo-1992 iwuphawu oluhambisana neChengdu Holy Cryogenic Equipment Company eShayina. I-HL Cryogenic Equipment izibophezele ekwakhiweni nasekukhiqizweni kwe-High Vacuum Insulated Cryogenic Piping System kanye ne-Support Equipment ehlobene nayo.
