ʻO ka epitaxy beam molecular, a i ʻole MBE, kahi ʻenehana hou no ka ulu ʻana i nā ʻili lahilahi kiʻekiʻe o nā kristal ma nā substrates kristal. I nā kūlana vacuum ultra-kiʻekiʻe, ua lako ka umu hoʻomehana me nā ʻano ʻāpana āpau e pono ai a hoʻopuka i ka mahu, ma o nā lua i hana ʻia ma hope o ka collimating beam atomic a molecular beam paha, ka injection pololei i ka mahana kūpono o ka substrate kristal hoʻokahi, e kaohi ana i ka beam molecular i ka substrate scanning i ka manawa like, hiki iā ia ke hana i nā mole a i ʻole nā ​​​​atoms i loko o nā papa hoʻonohonoho kristal e hana i kahi ʻili lahilahi ma kahi substrate "ulu".

No ka hana maʻamau o nā lako MBE, pono e lawe mau ʻia ka naikokene wai maʻemaʻe kiʻekiʻe, ke kaomi haʻahaʻa a me ka naikokene wai maʻemaʻe loa i ke keʻena hoʻoluʻu o nā lako. Ma keʻano laulā, ʻo kahi pahu e hāʻawi ana i ka naikokene wai he kaomi puka ma waena o 0.3MPa a me 0.8MPa. Hiki ke hoʻoheheʻe maʻalahi ʻia ka naikokene wai ma -196 ℃ i loko o ka naikokene i ka wā o ka lawe ʻana i ka pipeline. Ke hoʻoheheʻe ʻia ka naikokene wai me ka lakio kinoea-wai ma kahi o 1:700 i loko o ka pipeline, e noho ia i kahi nui o ke kahe naikokene wai a hōʻemi i ke kahe maʻamau ma ka hopena o ka pipeline naikokene wai. Eia kekahi, i loko o ka pahu mālama naikokene wai, aia paha he mau ʻōpala i hoʻomaʻemaʻe ʻole ʻia. I loko o ka pipeline naikokene wai, ʻo ka noho ʻana o ka ea pulu e alakaʻi pū i ka hana ʻana o ka ʻōpala hau. Inā hoʻokuʻu ʻia kēia mau mea haumia i loko o nā lako, e hōʻino ia i nā lako.

No laila, lawe ʻia ka naikokene wai i loko o ka pahu mālama waho i nā lako MBE i loko o ka hale hana lepo ʻole me ka pono kiʻekiʻe, kūpaʻa a me ka maʻemaʻe, a me ke kaomi haʻahaʻa, ʻaʻohe naikokene, ʻaʻohe haumia, 24 mau hola keu ʻole, ʻo ia ʻōnaehana hoʻokele halihali he huahana kūpono.
