Takaitaccen Bayani game da Epitaxy na Molecular Beam (MBE)
An ƙirƙiro fasahar Molecular Beam Epitaxy (MBE) a shekarun 1950 don shirya kayan fim na semiconductor masu siriri ta amfani da fasahar fitar da iskar gas. Tare da haɓaka fasahar injinan iska mai matuƙar girma, an faɗaɗa amfani da fasaha zuwa fannin kimiyyar semiconductor.
Dalilin binciken kayan semiconductor shine buƙatar sabbin na'urori, waɗanda zasu iya inganta aikin tsarin. A gefe guda kuma, sabbin fasahar kayan aiki na iya samar da sabbin kayan aiki da sabbin fasahohi. Epitaxy na ƙwayoyin halitta (MBE) fasaha ce mai ƙarfi ta injinan iska don haɓakar Layer na epitaxial (yawanci semiconductor). Yana amfani da hasken zafi na atoms ko ƙwayoyin da ke shafar substrate guda ɗaya na lu'ulu'u. Halayen injinan iska masu ƙarfi na tsari suna ba da damar yin ƙarfe a cikin wuri da haɓaka kayan rufi akan sabbin saman semiconductor da aka girma, wanda ke haifar da hanyoyin haɗin da ba su da gurɓatawa.
Fasaha ta MBE
An gudanar da epitaxy na hasken kwayoyin halitta a cikin injin injin mai ƙarfi ko injin injin mai ƙarfi (1 x 10)-8Pa) muhalli. Mafi mahimmancin ɓangaren epitaxy na ƙwayoyin halitta shine ƙarancin adadin ajiyarsa, wanda yawanci yana ba da damar fim ɗin ya girma a cikin ƙarancin saurin 3000 nm a kowace awa. Irin wannan ƙarancin adadin ajiyar yana buƙatar isasshen sarari don cimma matakin tsafta iri ɗaya da sauran hanyoyin ajiyar.
Domin saduwa da injin tsabtace iska mai matuƙar girma da aka bayyana a sama, na'urar MBE (Knudsen cell) tana da yanayin sanyaya iska, kuma dole ne a kiyaye yanayin injin tsabtace iska mai matuƙar girma na ɗakin girma ta amfani da tsarin zagayawar ruwa na nitrogen. Nitrogen mai tsafta yana sanyaya zafin jiki na cikin na'urar zuwa 77 Kelvin (−196 °C). Yanayin zafi mai ƙarancin zafi zai iya ƙara rage abubuwan da ke cikin injin tsabtace iska da kuma samar da yanayi mafi kyau don adana siraran fina-finai. Saboda haka, ana buƙatar tsarin sanyaya iska na nitrogen mai tsafta don kayan aikin MBE don samar da isasshen nitrogen mai tsafta da -196 °C.

Kamfanin Kayan Aiki na HL Cryogenic ya lura da buƙatar tsarin sanyaya ruwa na MBE, da kuma tsarin fasaha mai ƙarfi don samun nasarar haɓaka tsarin sanyaya ruwa na MBE na musamman don fasahar MBE da kuma cikakken saitin injin tsabtace iska.edtsarin bututun mai, wanda aka yi amfani da shi a kamfanoni da yawa, jami'o'i da cibiyoyin bincike.
