He Poto mo te Molecular Beam Epitaxy (MBE)
I whakawhanakehia te hangarau o te Molecular Beam Epitaxy (MBE) i te tekau tau atu i 1950 hei whakarite i nga rawa kiriata angiangi semiconductor ma te whakamahi i te hangarau whakaetonga korehau.Na te whanaketanga o te hangarau korehau ultra-tiketike, kua horahia te tono o te hangarau ki te mara o te pūtaiao semiconductor.
Ko te hihiri o te rangahau rauemi semiconductor ko te tono mo nga taputapu hou, ka pai ake te mahi o te punaha.Ka huri, ka whakaputahia e te hangarau rauemi hou nga taputapu hou me nga hangarau hou.Ko te epitaxy kurupae rapoi (MBE) he hangarau korehau teitei mo te tipu o te paparanga epitaxial (te nuinga o te wa whakangao).Ka whakamahia e ia te kurupae wera o nga ngota puna, ngota ngota ranei e pa ana ki te tïpako karaihe kotahi.Ko nga ahuatanga korehau tino teitei o te mahi ka taea te whakarewatanga i roto i te waahi me te tipu o nga rawa whakaraerae i runga i nga mata semiconductor hou tupu, ka hua mai he atanga kore poke.
Hangarau MBE
I mahia te epitaxy kurupae rapoi i roto i te korehau teitei, te korehau tino teitei ranei (1 x 10-8Pa) taiao.Ko te mea tino nui o te epitaxy kurupae rapoi ko te iti o te reiti waipara, ko te tikanga ka taea e te kiriata te tipu epitaxial i te tere o te iti iho i te 3000 nm ia haora.Ko te iti o te reiti waipara e hiahia ana kia nui te korehau kia eke ki te taumata o te ma ki etahi atu tikanga tuku.
Hei whakatutuki i te korehau tino teitei e whakaahuatia ana i runga ake nei, ko te taputapu MBE （Knudsen cell） he paparanga whakamatao, a me mau tonu te taiao korehau tino teitei o te ruuma tipu ma te whakamahi i te punaha tohanga hauota wai.Ko te hauota wai ka whakamatao i te pāmahana o roto o te taputapu ki te 77 Kelvin (−196 °C).Ka taea e te taiao pāmahana iti te whakaheke ake i te ihirangi o nga poke i roto i te korehau me te whakarato i nga tikanga pai ake mo te tukunga o nga kiriata kikokore.Na reira, ka hiahiatia he punaha tohanga hauota hauota wai mo nga taputapu MBE ki te whakarato tonu me te pumau o -196 °C hauota wai.
Te Pūnaha Whakamao Nitrogen Liquid
Ko te nuinga o nga punaha tohanga hauota wai hauota, kei roto,
● tank cryogenic
● matua me te manga korehau jacketed putorino / korehau jacketed ngongo ngongo
● MBE whakawehe wāhanga motuhake me te korehau koti ngongo putorino
● momo maru maru maru takirere
● arai hau-wai
● tātari koti korehau
● pūnaha papu korehau hihiri
● Te whakamatao o mua me te horoi i te punaha whakamahana
Kua kite a HL Cryogenic Equipment Company i te hiahia o te punaha whakamahana hauota wai MBE, kua whakaritea te tuara hangarau kia angitu ai te whakawhanake i tetahi punaha miihini hauota wai MBE motuhake mo te hangarau MBE me te huinga katoa o te whakamaarama korehau.edpūnaha paipa, kua whakamahia i roto i te maha o nga umanga, whare wananga me nga whare rangahau.
HL Cryogenic Taputapu
Ko te HL Cryogenic Equipment i whakaturia i te 1992 he waitohu e hono ana ki a Chengdu Holy Cryogenic Equipment Company i Haina.Ko te HL Cryogenic Equipment e kaha ana ki te hoahoa me te hanga o te High Vacuum Insulated Cryogenic Piping System me nga Taputapu Tautoko e pa ana.
