Mashruucii Chip MBE Waxa La Dhamaystiray Sanadihii La Soo Dhaafay

Farsamada

Molecular beam epitaxy, ama MBE, waa farsamo cusub oo loogu talagalay kobcinta aflaanta khafiifka ah ee tayada sare leh ee crystals substrates crystals. In xaaladaha vacuum ultra-sare, by kariyaha kululaynta waxaa lagu qalabeeyaa dhammaan noocyada kala duwan ee qaybaha loo baahan yahay iyo dhalin uumi, iyada oo godad la sameeyay ka dib markii collimating beam atomic ama alwaax molecular, duritaanka tooska ah heerkulka ku habboon ee substrate crystal hal, koontaroolaya laydhka molecular si Isla mar ahaantaana iskaanka substrate-ka, waxay samayn kartaa molecules-ka ama atamka ee lakabyada toosan ee crystal si ay u sameeyaan filim khafiif ah oo ku saabsan substrate "koritaanka".

Hawlgalka caadiga ah ee qalabka MBE, nadiifinta sare, cadaadiska hooseeya iyo nitrogen dareeraha ultra-nadiif ah ayaa loo baahan yahay in si joogto ah oo joogto ah loogu qaado qolka qaboojinta ee qalabka. Guud ahaan, haan bixisa nitrogen dareere ah waxay leedahay cadaadis wax soo saar oo u dhexeeya 0.3MPa iyo 0.8MPa. nitrogen dareeraha at -196 ℃ ayaa si fudud u uumi galay nitrogen inta lagu jiro gaadiidka dhuumaha. Marka nitrogen dareeraha ah oo leh saamiga dareeraha gaaska ee ku saabsan 1:700 waa gaasta dhuumaha, waxay qabsan doontaa xaddi badan oo qulqulka nitrogen dareeraha ah waxayna yareyn doontaa socodka caadiga ah dhamaadka dhuumaha nitrogen dareeraha ah. Intaa waxaa dheer, haanta kaydinta nitrogen ee dareeraha ah, waxay u badan tahay inay jiraan qashin aan la nadiifin. Dhuumaha nitrogen ee dareeraha ah, jiritaanka hawada qoyan waxay sidoo kale horseedi doontaa jiilka barafka. Haddii wasakhdaas lagu sii daayo qalabka, waxay keeni doontaa dhaawac aan la saadaalin karin qalabka.

Sidaa darteed, nitrogen dareeraha ah ee taangiga kaydinta dibadda waxaa loo raray qalabka MBE ee ku jira aqoon-is-weydaarsiga boodhka-free oo leh waxtar sare leh, xasillooni iyo nadiif ah, iyo cadaadiska hooseeya, nitrogen ma jiro, wax wasakh ah, 24 saacadood oo aan kala go 'lahayn, nidaamka xakamaynta gaadiidka sida alaab tayo leh.

Ku habboon qalabka MBE

Laga soo bilaabo 2005, HL Qalabka Cryogenic (HL CRYO) waxay hagaajinaysay oo hagaajinaysay nidaamkan waxayna la shaqaynaysay soo-saareyaasha qalabka MBE ee caalamiga ah. Soosaarayaasha qalabka MBE, oo ay ku jiraan DCA, REBER, waxay xiriir iskaashi la leeyihiin shirkadeena. Soosaarayaasha qalabka MBE, oo ay ku jiraan DCA iyo REBER, ayaa iska kaashaday tiro badan oo mashaariic ah.

Riber SA waa bixiye caalami ah oo hormuud ka ah alaabada iyo adeegyada la xidhiidha cilmi-baarista semiconductor-ka iyo codsiyada warshadaha (MBE). Qalabka Riber MBE wuxuu dhigi karaa lakabyo dhuuban oo dhuuban substrate-ka, oo leh kontaroolo aad u sarreeya. Qalabka faaruqinta ee HL Cryogenic Equipment (HL CRYO) waxaa lagu qalabeeyay Riber SA Qalabka ugu weyn waa Riber 6000 kan ugu yarna waa Compact 21. Waa xaalad wanaagsan oo ay garteen macaamiisha.

DCA waa MBE-ga ugu horreeya ee oksaydhka adduunka. Laga soo bilaabo 1993, horumarinta habaysan ee farsamooyinka oksaydhka, kuleylka substrate-ka antioxidant iyo ilaha antioxidant ayaa la fuliyay. Sababtan awgeed, shaybaarro badan oo hormuud ah ayaa doortay tignoolajiyada oksijiinta ee DCA. Nidaamyada semiconductor MBE isku dhafan ayaa laga isticmaalaa adduunka oo dhan. Nidaamka wareegga wareegga nitrogen ee dareeraha ah ee VJ ee Qalabka Cryogenic Equipment (HL CRYO) iyo qalabka MBE ee noocyo badan oo DCA ah ayaa leh waayo-aragnimada u dhigma ee mashruucyo badan, sida qaabka P600, R450, SGC800 iwm.
