ʻO ka molecular beam epitaxy, a i ʻole MBE, he ʻenehana hou no ka ulu ʻana i nā kiʻiʻoniʻoni lahilahi kiʻekiʻe o nā kristal ma nā substrate aniani. I loko o nā kūlana maloʻo ultra-kiʻekiʻe, ua hoʻolako ʻia ka umu wela me nā ʻano mea like ʻole a hoʻoulu i ka mahu, ma o nā lua i hana ʻia ma hope o ka collimating beam atomic a i ʻole molecular beam, hoʻokomo pololei ʻia i ka mahana kūpono o ka substrate kristal hoʻokahi, e hoʻomalu ana i ka molecular beam i. ʻO ka nānā ʻana i ka substrate i ka manawa like, hiki iā ia ke hana i nā molekala a i ʻole nā ​​mana i loko o nā papa alignment kristal e hana i kahi kiʻi ʻoniʻoni ma luna o kahi substrate "ulu".

No ka hana maʻamau o nā lako MBE, pono ka hoʻomaʻemaʻe kiʻekiʻe, ka haʻahaʻa haʻahaʻa a me ka ultra-clean liquid nitrogen e hoʻomau mau ʻia a paʻa i ka lawe ʻana i ke keʻena hoʻoluʻu o nā mea hana. Ma keʻano maʻamau, ʻo kahi pahu e hāʻawi ana i ka nitrogen wai i kahi kaomi puka ma waena o 0.3MPa a me 0.8MPa. ʻO ka nitrogen wai ma -196 ℃ ua maʻalahi ka vaporized i ka nitrogen i ka wā o ka lawe ʻana i ka pipeline. Once ka wai naikokene me ka kinoea-wai lākiō o e pili ana i 1:700 ua gasified i loko o ka pipeline, e noho i ka nui o ka wai naikokene kahe kahe a hoemi i ka maʻamau kahe ma ka hope o ka wai naikokene pipeline. Eia kekahi, i loko o ka pahu hoʻopaʻa wai nitrogen, aia paha nā ʻōpala i hoʻomaʻemaʻe ʻole ʻia. I loko o ka pipeline naikokene wai, e alakaʻi ka noho ʻana o ka ea pulu i ka hana o ka hau hau. Inā hoʻokuʻu ʻia kēia mau mea haumia i loko o nā mea hana, e hoʻopōʻino ʻole ʻia i nā mea hana.

No laila, lawe ʻia ka wai nitrogen i loko o ka pahu waiho waho i nā lako MBE i ka hale hana lepo ʻole me ka hana kiʻekiʻe, kūpaʻa a me ka maʻemaʻe, a me ka haʻahaʻa haʻahaʻa, ʻaʻohe nitrogen, ʻaʻohe haumia, 24 mau hola me ka pau ʻole, ʻo ia ka ʻōnaehana hoʻokele. he huahana kūpono.
