I-Molecular Beam Epitaxy (MBE) iyindlela enembe kakhulu esetshenziselwa ukwenza amafilimu amancanyana nama-nanostructures okusebenza okuhlukahlukene, okuhlanganisa amadivaysi e-semiconductor, i-optoelectronics, ne-quantum computing. Enye yezinselelo ezibalulekile ezinhlelweni ze-MBE ukugcina amazinga okushisa aphansi kakhulu, okuyilaphoipayipi le-vacuum jacketeds (VJP) iyangena. Lawa mapayipi athuthukile abalulekile ekuqinisekiseni ukulawula okushisayo emakamelweni e-MBE, okuwenza abe ingxenye ebaluleke kakhulu ekuzuzeni ukukhula kwekhwalithi ephezulu kwezinto ezingeni le-athomu.
Yini i-Molecular Beam Epitaxy (MBE)?
I-MBE iwuhlelo lokubeka olufaka phakathi ukubekwa okulawulwayo kwemishayo ye-athomu noma yamangqamuzana ku-substrate endaweni enevacuum ephezulu. Inqubo idinga ukulawula izinga lokushisa okunembile ukuze kuzuzwe izinto ezibonakalayo ezifunwayo, okwenza ukuphathwa kokushisa kube yinto ebalulekile. Ezinhlelweni ze-MBE,vacuum jacketed amapayipiasetshenziselwa ukuthwala uketshezi namagesi e-cryogenic, okuqinisekisa ukuthi i-substrate ihlala ezingeni lokushisa elifanele ngesikhathi senqubo yokubeka.
Indima ye-Vacuum Jacketed Pipes ku-MBE Systems
Kubuchwepheshe be-MBE,vacuum jacketed amapayipingokuyinhloko asetshenziselwa ukuthutha ama-cryogens afana ne-nitrogen ewuketshezi kanye ne-helium ewuketshezi ukupholisa igumbi le-MBE kanye nezingxenye ezihlobene. Amapayipi ahlanganisa ipayipi elingaphakathi elibamba uketshezi lwe-cryogenic, elizungezwe ijakhethi yangaphandle evikelayo enongqimba lwe-vacuum. Lokhu kufakwa kwe-vacuum kunciphisa ukudluliswa kokushisa, kuvimbela ukuguquguquka kwezinga lokushisa nokuqinisekisa ukuthi isistimu igcina amazinga okushisa aphansi kakhulu adingekayo ku-MBE.
Izinzuzo Ukusebenzisa Vacuum Jacketed Amapayipi ku MBE Technology
Ukusetshenziswa kwevacuum jacketed amapayipikubuchwepheshe be-MBE inikeza izinzuzo ezimbalwa. Okokuqala, baqinisekisa ukulawulwa okushisayo okunembile okudingekayo ekufakweni kwefilimu emincane yekhwalithi ephezulu, okubalulekile ekuzuzeni ukukhula kwempahla efanayo. Okwesibili, basiza ukunciphisa ingozi yokungcola endaweni ye-MBE ngokugcina ubuqotho be-vacuum. Okokugcina,vacuum jacketed amapayipiukwenza ngcono ukusebenza kahle jikelele kohlelo lwe-MBE ngokunciphisa ukubilisa koketshezi lwe-cryogenic, okuholela ezindlekweni eziphansi zokusebenza kanye nokuphila kwesistimu okude.
Ikusasa lamapayipi anejakhethi ye-Vacuum kuzicelo ze-MBE
Njengoba ubuchwepheshe be-MBE buqhubeka nokuvela futhi izidingo zokunemba okuphezulu zikhula,vacuum jacketed amapayipiizodlala indima ebaluleke kakhulu. Ukuqanjwa kwezinto ezintsha zokufakelwa kanye nomklamo kuzothuthukisa ukusebenza kwala mapayipi, kuthuthukise ukusebenza kahle kwamandla kwezinhlelo ze-MBE futhi kuvumele ukwenziwa kwezinto ezithuthuke kakhulu. Njengoba izimboni ezifana nokukhiqizwa kwe-semiconductor kanye ne-quantum computing ziqhubeka nokukhula, isidingo sezixazululo ezithembekile nezisebenzayo zokuphatha okushisayo, njengevacuum jacketed amapayipi, izokhula kuphela.
Ekuphetheni,vacuum jacketed amapayipiziyingxenye ebalulekile enqubweni ye-MBE, evumela ukulawula izinga lokushisa okunembayo kanye nokuqinisekisa ukufakwa ngempumelelo kwamafilimu amancanyana ekhwalithi ephezulu. Njengoba isidingo sezinto ezithuthukisiwe siqhubeka sikhuphuka, lawa mapayipi azohlala ebalulekile ekugcineni izindawo ezisezingeni eliphansi zokushisa ezidingekayo kubuchwepheshe be-MBE obusezingeni eliphezulu.
