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 ka ultra-high vacuum kūlana, e ka wela wela ua lako me na ano a pau e pono ai a hoopuka i ka mahu, ma o na lua i hanaia ma hope o collimating beam atomic a molekula kaola, pololei injection i ka pono wela o ka hookahi kristal substrate, kaohi molecular kukuna i ka substrate scanning i ka manawa like, hiki iā ia ke hana i nā molekele a i ʻole nā ​​mana i loko o ka kristal a alignment film ".

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 loko o ka hale hana lepo ʻole me ke kiʻekiʻe o ka pono, kūpaʻa a me ka maʻemaʻe, a me ka haʻahaʻa haʻahaʻa, ʻaʻohe nitrogen, ʻaʻohe haumia, 24 mau hola me ka hoʻopaʻa ʻole ʻia, ʻo ia ka ʻōnaehana kaʻa kaʻa he huahana kūpono.
