Umuyoboro ushyushya ukoresheje icyuma gikonjesha(VIP) igira uruhare runini mu nzego zitandukanye z’ikoranabuhanga rigezweho, cyane cyane muri sisitemu ya molekile (MBE).MBEni uburyo bukoreshwa mu gukora kristu za semiconductor nziza cyane, igikorwa cy'ingenzi mu bikoresho by'ikoranabuhanga bigezweho, harimo ibikoresho bya semiconductor, ikoranabuhanga rya laser, n'ibikoresho bigezweho. Kubungabunga ubushyuhe buri hasi cyane muri ibi bikorwa ni ngombwa, kandi umuyoboro ushyushya ukoresheje icyuma gifunga umwukaIkoranabuhanga rituma habaho ubwikorezi bwiza bw'amazi ahumanya kugira ngo abungabunge ibyo bintu bikenewe. Iyi blog izasuzuma uruhare n'akamaro kaumuyoboro ushyushya ukoresheje icyuma gifunga umwukamuri sisitemu za MBE.

Epitaxy y'umuraba wa molekile ni iki (MBE)?

Epitaksi y'urumuri rw'ibinyabutabire (MBE) ni inzira igenzurwa cyane yo gukura filime nto z'ibikoresho, ikunze gukoreshwa mu gukora semiconductors. Iyi nzira ibera ahantu hari umwuka mwinshi, aho imirasire ya atome cyangwa molekile yerekeza ku kintu, bigatuma kristu zikura ku gice ku kindi hamwe n'ubuyobozi buhamye. Kugira ngo iyi nzira ikomeze kuba nziza, hakenewe ubushyuhe buke cyane, ari nahoumuyoboro ushyushya ukoresheje icyuma gifunga umwukaikoranabuhanga riba ingenzi.

Uruhare rwaUmuyoboro urinda ubushyuhe mu cyuma in MBE Sisitemu

Umuyoboro ushyushya ukoresheje icyuma gikonjeshaikoreshwa muriMBEsisitemu zo gutwara ibintu bihumanya ikirere, nka azote y'amazi cyangwa heliyumu y'amazi, kugira ngo bikonjeshe ibice biri muri sisitemu. Ibi bintu bihumanya ikirere ni ingenzi cyane mu kubungabunga umwuka mwinshi cyane no kugenzura ubushyuheMBEsisitemu zisaba kugira ngo imikorere myiza irusheho kuba myiza. Iyo hatabayeho ubushyuhe buhagije, amazi ashyuha vuba, bigatuma ubushyuhe budahindagurika kandi bikabangamira ireme ry'imikurire ya epitaxial.

Urukuta rw’ingufu ruri hagati y’imiyoboro y’imbere n’iy’inyuma rukora nk’icyuma gikingira ubushyuhe neza cyane, kigabanya uburyo ubushyuhe bwiyongera binyuze mu gukwirakwiza no gukwirakwiza amazi mu kirere, ari na byo bintu by’ingenzi bitera ihindagurika ry’ubushyuhe mu buryo bushyushye.

KukiUmuyoboro urinda ubushyuhe mu cyuma Ni ingenzi kuriMBE Sisitemu

Ubuhanga bwo hejuru bukenewe muriMBEsisitemu zitumaumuyoboro ushyushya ukoresheje icyuma gifunga umwuka ngombwa. Ikoranabuhanga rya VIP rigabanya ibyago byo gutemba amazi ashyushye, bishobora kubangamira uburyo bwo gukonjesha no kudahindagurika kw'ibikoresho byo mu bwoko bwa vacuum. Byongeye kandi, gukoresha imiyoboro ifunganye ikoreshwa mu bikoresho byo mu bwoko bwa vacuum bifasha kugabanya ikiguzi cy'ingufu binyuze mu kugabanya gukenera imbaraga z'inyongera zo gukonjesha, bikongera imikorere myiza yabyo muri rusange.

Indi nyungu yo gukoreshaumuyoboro ushyushya ukoresheje icyuma gifunga umwukamuriMBEsisitemu ni uburyo ihora yizewe. Imiyoboro yagenewe kubungabunga ubushyuhe mu gihe kirekire, bigatuma ikora neza mu bice by’ingufu cyane nkaMBE.
