ʻO ka pōkole o ka Molecular Beam Epitaxy (MBE)
Ua hoʻomohala ʻia ka ʻenehana o Molecular Beam Epitaxy (MBE) i nā makahiki 1950 e hoʻomākaukau i nā mea ʻili lahilahi semiconductor me ka hoʻohana ʻana i ka ʻenehana hoʻoheheʻe vacuum. Me ka hoʻomohala ʻana o ka ʻenehana vacuum ultra-high, ua hoʻonui ʻia ka hoʻohana ʻana o ka ʻenehana i ke kahua o ka ʻepekema semiconductor.
ʻO ke kumu o ka noiʻi ʻana i nā mea semiconductor ka noiʻi no nā mea hana hou, kahi e hoʻomaikaʻi ai i ka hana o ka ʻōnaehana. Ma ka huli ʻana, hiki i ka ʻenehana mea hou ke hana i nā lako hou a me nā ʻenehana hou. ʻO ka molecular beam epitaxy (MBE) kahi ʻenehana vacuum kiʻekiʻe no ka ulu ʻana o ka papa epitaxial (maʻamau semiconductor). Hoʻohana ia i ke kukuna wela o nā ʻātoma kumu a i ʻole nā molekula e hoʻopilikia ana i ka substrate kristal hoʻokahi. ʻO nā ʻano vacuum kiʻekiʻe loa o ke kaʻina hana e ʻae i ka metallization in-situ a me ka ulu ʻana o nā mea insulating ma nā ʻili semiconductor i ulu hou ʻia, e hopena ana i nā interfaces haumia ʻole.
ʻenehana MBE
Ua hoʻokō ʻia ka epitaxy beam molecular i loko o kahi vacuum kiʻekiʻe a i ʻole ka vacuum ultra-kiʻekiʻe (1 x 10-8Kaiapuni Pa). ʻO ka ʻaoʻao koʻikoʻi o ka epitaxy beam molecular ʻo ia kona helu hoʻokaʻawale haʻahaʻa, kahi e ʻae pinepine ai i ke kiʻiʻoniʻoni e ulu epitaxial ma ka wikiwiki o ka emi ma mua o 3000 nm i kēlā me kēia hola. Pono kēlā helu hoʻokaʻawale haʻahaʻa i kahi vacuum kiʻekiʻe e hoʻokō ai i ka pae like o ka maʻemaʻe e like me nā ʻano hoʻokaʻawale ʻē aʻe.
I mea e hoʻokō ai i ka vacuum ultra-kiʻekiʻe i wehewehe ʻia ma luna, aia ka hāmeʻa MBE (kelepona Knudsen) i kahi papa hoʻoluʻu, a pono e mālama ʻia ke kaiapuni vacuum ultra-kiʻekiʻe o ke keʻena ulu me ka hoʻohana ʻana i kahi ʻōnaehana kahe naikokene wai. Hoʻomaʻalili ka naikokene wai i ka mahana o loko o ka hāmeʻa i 77 Kelvin (−196 °C). Hiki i ke kaiapuni mahana haʻahaʻa ke hōʻemi hou aku i ka nui o nā haumia i loko o ka vacuum a hāʻawi i nā kūlana maikaʻi aʻe no ka waiho ʻana o nā ʻili lahilahi. No laila, pono kahi ʻōnaehana kahe hoʻoluʻu naikokene wai i hoʻolaʻa ʻia no nā lako MBE e hāʻawi i kahi lako mau a paʻa o ka naikokene wai -196 °C.
ʻŌnaehana Hoʻolulu Naikokene Wai
ʻO ka ʻōnaehana hoʻolaha hoʻoluʻu naikokene wai vacuum e komo pū ana me,
● pahu waiola
● paipu ʻaʻahu vacuum nui a me ka lālā / hose ʻaʻahu vacuum
● MBE mea hoʻokaʻawale pae kūikawā a me ka paipu hoʻopau i uhi ʻia i ka vacuum
● nā kiwikā ʻaʻahu vacuum like ʻole
● pale kinoea-wai
● kānana ʻaʻahu ʻūlū
● ʻōnaehana pamu hakahaka ikaika
● ʻŌnaehana hoʻomaʻalili mua a me ka hoʻomaʻemaʻe hou ʻana
Ua ʻike ʻo HL Cryogenic Equipment Company i ke koi o ka ʻōnaehana hoʻoluʻu naikokene wai MBE, kahi iwi kuamoʻo loea i hoʻonohonoho pono ʻia e hoʻomohala pono i kahi ʻōnaehana hoʻoluʻu naikokene wai MBE kūikawā no ka ʻenehana MBE a me kahi hoʻonohonoho piha o ka vacuum insulation.edʻōnaehana paipu, ka mea i hoʻohana ʻia ma nā ʻoihana he nui, nā kulanui a me nā ʻoihana noiʻi.
Nā Lako Hana Cryogenic HL
ʻO HL Cryogenic Equipment, i hoʻokumu ʻia i ka makahiki 1992, he hōʻailona ia e pili ana iā Chengdu Holy Cryogenic Equipment Company ma Kina. Ua kūpaʻa ʻo HL Cryogenic Equipment i ka hoʻolālā a me ka hana ʻana o ka High Vacuum Insulated Cryogenic Piping System a me nā lako kākoʻo e pili ana.
