ʻO ka epitaxy beam Molecular, a i ʻole MBE, kahi hana hou no ka hoʻoulu ʻana i nā kiʻi ʻoniʻoni lahilahi kiʻekiʻe o nā aniani ma nā aniani substrates. I nā kūlana uila kiʻekiʻe loa, e ka umu hoʻomehana hoʻomāhuahua me nā ʻano o nā pono e koi ʻia a hoʻonui i ka mahu, ma o nā puka i hana ʻia ma hope o ka hoʻopili ʻana i ka lāʻau atomic a i ʻole ka lāʻau mole mole, hoʻopiʻi pono i ka mahana kūpono o ka substrate aniani hoʻokahi, e kaohi ana i ka lāʻau mole i ke ʻimi ʻana i ka substrate i ka manawa like, hiki iā ia ke hana i nā molaki a i ʻole nā ​​ʻoma i nā papa hoʻonohonoho aniani e hana i kahi kiʻi lahilahi ma kahi "ulu" substrate.

No ka hana maʻamau o ka pono MBE, pono ke hoʻomau ʻia ka maʻemaʻe kiʻekiʻe, kaomi haʻahaʻa a me ka nitrogen wai piha maʻemaʻe a lawe mau ʻia i ka lumi hōʻoluʻolu o nā pono. Ma ka laulaha, kahi pahu e hāʻawi i ka nitrogen wai i loaʻa kahi kaomi puka ma waena o 0.3MPa a me 0.8MPa. Hoʻohui maʻalahi ʻia ka nitrogen liu ma -196 into i loko o nitrogen i ka lawe ʻana o ka pipeline I ka manawa e hoʻoheheʻe ʻia ai ka nitrogen wai me ka lakio gas-wai ma kahi o 1: 700 i ka paipu, e noho ia i kahi nui o ke kahe o ka nitrogen wai a hoʻemi i ke kahe maʻamau i ka hopena o ka paipu nitrogen wai. Hoʻohui ʻia, i loko o ka pahu mālama mālama nitrogen wai, aia paha he ʻōpala i hoʻomaʻemaʻe ʻole ʻia. I ka paipu nitrogen wai, ke alakaʻi o ka ea pulu e alakaʻi i ka hanauna o ka hau hau. Inā hoʻokuʻu ʻia kēia mau impurities i loko o nā lakohana, e kumu ia i nā pōʻino i ʻike ʻole ʻia i nā lakohana.

No laila, lawe ʻia ka nitrogen wai i loko o ka pahu waihona waho i nā pono MBE i loko o ka hale hana manuahi ʻole me ke kiʻekiʻe kiʻekiʻe, kūpaʻa a maʻemaʻe, a me ke kaomi haʻahaʻa, ʻaʻohe nitrogen, ʻaʻohe impurities, 24 mau hola i kāpae ʻole ʻia, he huahana kūpono.
