Imashini ikoresha ikoranabuhanga rya Molecular Beam Epitaxy, cyangwa MBE, ni uburyo bushya bwo gutera filime ntoya z’ubuziranenge ku mashini zikoresha kristu. Mu bihe byo kuzura cyane, icyuma gishyushya gifite ubwoko bwose bw’ibice bikenewe kandi kikabyara umwuka, binyuze mu myobo ikorwa nyuma yo gukurura icyuma cya atome cyangwa kristu, kikayishyira mu bushyuhe bukwiye bwa kristu imwe, kikagenzura icyuma cya molecular kuri kristu isuzuma icyarimwe, gishobora gutuma molecules cyangwa atome ziri mu byiciro bya kristu zikora filime ntoya kuri kristu "growth".

Kugira ngo ibikoresho bya MBE bikore neza, ni ngombwa ko bigezwa mu cyumba gikonjesha ibikoresho mu buryo busanzwe, umwuka muto, na azote y'amazi isukuye cyane. Muri rusange, ikigega gitanga azote y'amazi gifite umuvuduko uri hagati ya 0.3MPa na 0.8MPa. Azote y'amazi kuri -196℃ ihinduka azote mu buryo bworoshye mu gihe cyo gutwara umuyoboro. Iyo azote y'amazi ifite igipimo cya gazi n'amazi kingana na 1:700 imaze gushyirwamo umwuka mu muyoboro, izafata umwanya munini w'amazi ya azote kandi igabanye umuvuduko usanzwe ku mpera y'umuyoboro wa azote y'amazi. Byongeye kandi, mu kigega cyo kubika azote y'amazi, hashobora kubaho imyanda itarasukurwa. Mu muyoboro wa azote y'amazi, kubaho k'umwuka utose bizatuma habaho urubura. Iyo iyo myanda isukuye mu bikoresho, bizatera kwangirika ku buryo butunguranye ku bikoresho.

Bityo rero, azote y'amazi iri mu kigega cyo kubikamo ibintu hanze ijyanwa mu bikoresho bya MBE mu iduka ridafite ivumbi rifite imikorere myiza, ituje kandi risukuye, kandi umuvuduko muke, nta azote, nta mwanda, amasaha 24 nta guhagarara, ubwo buryo bwo kugenzura ubwikorezi ni umusaruro wujuje ibisabwa.
