Ipayipi elifakwe ku-vacuum(I-VIP) idlala indima ebalulekile emikhakheni ehlukahlukene yobuchwepheshe obuphakeme, ikakhulukazi ezinhlelweni ze-molecular beam epitaxy (MBE).Thela indluIngabe inqubo esetshenziselwa ukudala amakristalu e-semiconductor asezingeni eliphakeme, inqubo ebucayi e-elekthronikhi yanamuhla, kufaka phakathi amadivaysi e-semiconductor, ubuchwepheshe be-laser kanye nezinto ezithuthukisiwe. Ukugcina amazinga okushisa aphansi we-ultra ngalezi zinqubo kubalulekile, futhi Ipayipi elifakwe ku-vacuumUbuchwepheshe buqinisekisa ukuthuthwa okusebenzayo koketshezi lwe-cryogenic ukugcina lezo zimo ezidingekayo. Le bhulogi izohlola indima nokubaluleka kweIpayipi elifakwe ku-vacuumezinhlelweni ze-MBE.

Yini i-molecular beam epitaxy (Thela indlu)?

I-Molecular Beam Epitaxy (Thela indlu) Inqubo elawulwa kakhulu yokukhula amafilimu amancanyana akhulayo wezinto zokwakha, evame ukusetshenziswa ekukhiqizeni ama-semiconductors. Inqubo yenzeka endaweni ephezulu ye-vacuum, lapho imishayo yama-athomu noma ama-molecule aqondiswe khona engxenyeni engezansi, evumela ukukhula kwamakristalu ngongqikithi wamakristalu ngokulawulwa okuqondile. Ukuze ugcine ubuqotho bale nqubo, amazinga okushisa aphansi kakhulu ayadingeka, okuyiphiIpayipi elifakwe ku-vacuumubuchwepheshe bubaluleke kakhulu.

Indima yeIpayipi elifakwe ku-vacuum in Thela indlu Amasistimu

Ipayipi elifakwe ku-vacuumisetshenziswa ngaphakathiThela indluAmasistimu okuhambisa uketshezi lwe-cryogenic, njenge-nitrogen ye-liquid noma i-helium ewuketshezi, ezingxenyeni ezipholile ngaphakathi kohlelo. Lezi ziphuzo ze-cryogenic zibalulekile ekugcineni ukulondolozwa kwe-vacuum ephezulu kanye nokulawulwa kokushisa okuthiThela indluizinhlelo zidinga ukusebenza kahle. Ngaphandle kokufakelwa okusebenzayo, uketshezi lwe-cryogenic luzofudumeza ngokushesha, okuholele ekumeni kwamazinga okushisa kanye nokuyekethisa ikhwalithi yokukhula kwe-epitaxial.

Le khasiIpayipi elifakwe ku-vacuumIqinisekisa ukulahleka okuncane okushisayo ngesikhathi sokuhanjiswa kwalolu ketshezi lwe-crygenic. Ungqimba lwe-vacuum phakathi kwamapayipi angaphakathi nangaphandle lusebenza njenge-insulator esebenza kahle kakhulu, ukunciphisa ukudluliswa kokushisa ngokutholwa kanye nokuxhuma, okuyizimbangela zokuguquguquka kwezinga lokushisa ezinhlelweni ze-crygenic.

NgobaniIpayipi elifakwe ku-vacuum KubalulekileThela indlu Amasistimu

Ukucaciswa okuphezulu okudingekayoThela indluIzinhlelo zenzaIpayipi elifakwe ku-vacuum isidingo. Ubuchwepheshe be-VIP bunciphisa ubungozi bokubila kwe-cryogenic ketshezi, okungaphazamisa ukuqina kohlelo nokuqina kwe-vacuum. Ngokwengeziwe, ukusetshenziswa kwamapayipi we-Vacuum Insuum kusiza ukunciphisa izindleko zamandla ngokunciphisa isidingo samandla okupholisa angeziwe, ukuthuthukisa ukusebenza kahle kohlelo.

Enye inzuzo yokusebenzisaIpayipi elifakwe ku-vacuumphakathi kwa-Thela indluIzinhlelo ukuthembeka kwayo isikhathi eside. Amapayipi aklanyelwe ukugcina ukufakwa okushisayo ngaphezulu kwezikhathi ezengeziwe, aqinisekise ukusebenza okungaguquki ezindaweni ezibucayi kakhulu ezifanaThela indlu.

Isiphetho:Ipayipi elifakwe ku-vacuum KuthuthukisaThela indlu Ukusebenza kwesistimu

Ukuhlanganiswa kweIpayipi elifakwe ku-vacuumphakathi kwa-Thela indluIzinhlelo zibalulekile ukuze zilondoloze ukunemba okuphezulu nokuqina kwalezi zinqubo zifuna. Ngokunciphisa ukudluliselwa kokushisa, ubuchwepheshe be-VIP buqinisekisa ukuthi uketshezi lwe-cryogenic luhlala emazingeni okushisa aphansi aphansi, ukukhuthaza ukukhula okuphezulu kwe-semiconductor kanye nokunciphisa izindleko zokusebenza. Nga-Thela indluUbuchwepheshe buqhubeka buqhubekisa phambili, indima yeIpayipi elifakwe ku-vacuumEkusekeleni lezi zinqubo kuzohlala kubaluleke kakhulu.
