Umuyoboro wa Vacuum(VIP) igira uruhare runini mubice bitandukanye byubuhanga buhanitse, cyane cyane muri sisitemu ya molekile beam epitaxy (MBE).MBEni tekinike ikoreshwa mugukora sisitemu yo mu rwego rwohejuru ya kirisiti, inzira ikomeye muri elegitoroniki igezweho, harimo ibikoresho bya semiconductor, tekinoroji ya laser, nibikoresho bigezweho. Kugumana ubushyuhe burenze urugero muri ibi bikorwa ni ngombwa, kandi Umuyoboro wa vacuumtekinoroji itanga uburyo bwiza bwo gutwara ibintu bya kirogenike kugirango ibungabunge ibyo bikenewe. Iyi blog izasesengura uruhare nakamaro kaUmuyoboro wa vacuummuri sisitemu ya MBE.

Niki Epitaxy ya Molecular Beam (MBE)?

Molecular beam epitaxy (MBE) ni inzira igenzurwa cyane mukuzamura firime yoroheje yibikoresho, bikunze gukoreshwa mugukora semiconductor. Inzira ibera ahantu hahanamye cyane, aho imirishyo ya atome cyangwa molekile yerekejwe kuri substrate, bigatuma habaho gukura-ku-byiciro bya kristu hamwe no kugenzura neza. Kugirango ubungabunge ubusugire bwiki gikorwa, ubushyuhe buke cyane burakenewe, nihoUmuyoboro wa vacuumikoranabuhanga riba ngombwa.

Uruhare rwaUmuyoboro wa Vacuum in MBE Sisitemu

Umuyoboro wa Vacuumni Byakoreshejwe inMBEsisitemu yo gutwara ibintu bya kirogenike, nka azote cyangwa amazi ya helium, kugirango ibice bikonje muri sisitemu. Aya mavuta ya kirogenike ningirakamaro mugukomeza icyuho kinini cyane no kugenzura ubushyuhe ibyoMBEsisitemu isaba imikorere myiza. Hatabayeho gukingirwa neza, amavuta ya kirogenike yashyuha vuba, bigatuma ubushyuhe budahungabana kandi bikabangamira ubwiza bwikura rya epitaxial.

UwitekaUmuyoboro wa vacuumitanga igihombo gito cyumuriro mugihe cyo gutwara ayo mazi ya kirogenike. Icyuho cya vacuum kiri hagati yimiyoboro yimbere ninyuma ikora nka insuliranteri ikora neza, igabanya ihererekanyabubasha ikoresheje imiyoboro hamwe na convection, zikaba arizo mpamvu nyamukuru zitera ihindagurika ryubushyuhe muri sisitemu ya cryogenic.

Kubera ikiUmuyoboro wa Vacuum Ni ngombwa kuriMBE Sisitemu

Ibisobanuro bihanitse bisabwa muriMBESisitemu ikoraUmuyoboro wa vacuum igikenewe. Ikoranabuhanga rya VIP rigabanya ibyago byo guturika kwa kirogenike, bishobora guhungabanya sisitemu yo gukonja no guhagarara neza. Byongeye kandi, gukoresha imiyoboro ya vacuum ikingira ifasha kugabanya ikiguzi cyingufu mukugabanya ingufu zikenewe zo gukonjesha, kuzamura imikorere ya sisitemu muri rusange.

Iyindi nyungu yo gukoreshaUmuyoboro wa vacuuminMBEsisitemu nigihe kirekire cyo kwizerwa. Imiyoboro yashizweho kugirango ibungabunge ubushyuhe bwumuriro mugihe kinini, itanga imikorere ihamye mubidukikije byoroshye nkaMBE.

Umwanzuro:Umuyoboro wa Vacuum GutezimbereMBE Imikorere ya sisitemu

Kwishyira hamwe kwaUmuyoboro wa vacuuminMBEsisitemu ningirakamaro mugukomeza ibisobanuro bihamye kandi bihamye izi nzira zisaba. Mugabanye ihererekanyabubasha, tekinoroji ya VIP iremeza ko amavuta ya kirogenike aguma ku bushyuhe buke busabwa, bigatuma imikurire ya semiconductor ikura neza kandi igabanya ibiciro byakazi. NkMBEikoranabuhanga rikomeje gutera imbere, uruhare rwaUmuyoboro wa vacuummugushyigikira izi nzira zizakomeza kuba ingenzi.
