I-Molecular Beam Epitaxy (MBE) iyindlela eqondile kakhulu esetshenziselwa ukwenza amafilimu amancanyana kanye nama-nanostructures ezicelo ezahlukahlukene, kufaka phakathi amadivaysi e-semiconductor, kanye ne-computing ye-quantum. Enye yezinselelo ezibalulekile ezinhlelweni ze-MBE igcina amazinga okushisa aphansi kakhulu, okulaphoIpayipi le-vacuum jacketI-S (VJP) idlale. Lawa mapayipi athuthukile abalulekile ekuqinisekiseni ukulawulwa okushisayo kumakamelo aseMBE, abenze ukuba kube nengxenye ebaluleke kakhulu ekuzuzeni ukukhula okuseqophelweni eliphezulu kwezinto ezisetshenziswayo ezingeni le-athomu.
Uyini uMolecular Beam Epitaxy (MBE)?
I-MBE yindlela yokubeka imigomo ehilela ukukhishwa okulawulwa kwama-athomu noma ama-molecular ama-molecular angena engxenyeni engezansi endaweni ephezulu ye-vacuum. Inqubo idinga ukulawulwa kokushisa okuqondile ukufeza izakhiwo ezibonakalayo ezifunwa, ezenza ukuphathwa kwe-thermal kube yinto ebucayi. Ezinhlelweni ze-MBE,Amapayipi we-vactuumzisetshenziselwa ukuthwala uketshezi lwama-cryogenic kanye namagesi, ukuqinisekisa ukuthi i-substrate ihlala ekushiseni okulungile ngesikhathi senqubo yokubekwa.
Indima yamapayipi we-vacuum jacket ezinhlelweni ze-MBE
Kubuchwepheshe be-MBE,Amapayipi we-vactuumngokuyinhloko isetshenziselwa ukuthutha ama-cryrogens afana ne-nitrogen ye-litrogen kanye ne-helium ewuketshezi ukupholisa i-MBER Chamber nezakhi ezihlobene. Amapayipi aqukethe ipayipi elingaphakathi eliphethe uketshezi lwe-cryogenic, ezungezwe yijakhethi engaphandle efaka ungqimba. Lokhu kufakwa kwe-vacuum kunciphisa ukudluliswa kokushisa, ukuvimbela ukuguquguquka kokushisa nokuqinisekisa ukuthi uhlelo lugcina amazinga okushisa aphansi kakhulu adingekayo ku-MBE.
Izinzuzo zokusebenzisa amapayipi we-vacuum jacketed e-MBE Technology
Ukusetshenziswa kweAmapayipi we-vactuumKubuchwepheshe be-MBE bunikeza izinzuzo eziningana. Okokuqala, baqinisekisa ukulawulwa okunembile okushisayo okudingekayo ukuze kufakwe imali ephakeme yefilimu ephezulu, okubalulekile ekufezekiseni ukukhula okufana nokwamanye amazwe. Okwesibili, basiza ekunciphiseni ubungozi bokungcoliswa kwemvelo ye-MBE ngokugcina ubuqotho be-vacuum. Okokugcina,Amapayipi we-vactuumThuthukisa ukusebenza kahle kohlelo lwe-MBE ngokunciphisa amathumba we-Crygenic Liquid, okuholela kwizindleko eziphansi zokusebenza kanye nama-Lifespan amade.
Ikusasa lamapayipi we-vacuum jacket ezihlolweni ze-MBE
Njengoba ubuchwepheshe be-MBE buqhubeka nokuvela futhi kufunwa ukuthuthuka okuphezulu kukhule,Amapayipi we-vactuumuzodlala indima ebaluleke kakhulu. Izinto ezintsha kuzinto zokwehlukanisa kanye nokwakhiwa kuzothuthukisa ukusebenza kwalawa mapayipi, kuthuthukisa ukusebenza kahle kwamandla ezinhlezinhlelo ze-MBE futhi kuvuse amandla okuqamba kwezinto ezithuthukisiwe. Njengoba izimboni ezinjengezokwakha ze-semiconductor kanye ne-quantum computing ziyaqhubeka ukwandisa, isidingo sezixazululo ezithembekile nezisebenza kahle zokuphathwa kwe-thermal, njengeAmapayipi we-vactuum, izokhula kuphela.
Ekuphetheni,Amapayipi we-vactuumIngxenye ebalulekile kwinqubo ye-Mbe, inika amandla ukulawulwa okuqondile kokushisa kanye nokuqinisekisa ukubekwa ngempumelelo kwamafilimu aphezulu asezingeni eliphakeme. Njengoba isidingo sezinto ezithuthukisiwe siqhubeka sikhuphuka, la mapayipi azohlala ebalulekile ukuze ulondoloze izindawo zokushisa eziphansi ezidingekayo ukuze uthole ubuchwepheshe be-MBE.
