Ko te Molecular Beam Epitaxy (MBE) he tikanga tino tika e whakamahia ana hei hanga i ngā kiriata angiangi me ngā hanganga nano mō ngā momo tono, tae atu ki ngā taputapu semiconductor, optoelectronics, me te rorohiko kuantum. Ko tētahi o ngā wero matua i roto i ngā pūnaha MBE ko te pupuri i ngā pāmahana tino iti, koinei te wāhi epaipa kua hipokina ki te korehauKa whai wāhi mai ngā paipa matatau (VJP). He mea nui ēnei paipa matatau hei whakarite i te whakahaere wera i roto i ngā rūma MBE, ā, he mea nui rawa atu ēnei hei whakatutuki i te tipu kounga teitei o ngā rauemi i te taumata ngota.
He aha te Molecular Beam Epitaxy (MBE)?
He tikanga whakatakoto te MBE e uru ana ki te whakatakoto whakahaere o ngā hihi ngota ngota, ngota ngota rānei ki runga i tētahi papa i roto i tētahi taiao korehau-teitei. Me whakahaere tika te pāmahana mō tēnei tukanga kia tutuki ai ngā āhuatanga rauemi e hiahiatia ana, ā, he mea nui te whakahaere wera. I roto i ngā pūnaha MBE,ngā paipa kua hipokina ki te korehaue whakamahia ana hei kawe i ngā wai me ngā hau cryogenic, hei whakarite kia noho tonu te pāmahana o te papa i te wā e whakatakotoranga ana.
Te Tūranga o ngā Paipa Korehau i roto i ngā Pūnaha MBE
I roto i te hangarau MBE,ngā paipa kua hipokina ki te korehaue whakamahia ana hei kawe i ngā cryogens pērā i te hauota wai me te herium wai hei whakamatao i te rūma MBE me ngā wāhanga e pā ana. Ko ngā paipa he paipa o roto e pupuri ana i te wai cryogenic, e karapotia ana e te koti whakamahana o waho me te paparanga korehau. Ka whakaitihia e tēnei whakamahana korehau te whakawhiti wera, ka ārai i ngā piki me ngā heke o te pāmahana, ā, ka whakarite kia mau tonu te pūnaha i ngā pāmahana tino iti e hiahiatia ana mō te MBE.
Ngā Painga o te Whakamahi i ngā Paipa Korehau i roto i te Hangarau MBE
Te whakamahinga ongā paipa kua hipokina ki te korehauHe maha ngā painga o te hangarau MBE. Tuatahi, ka whakarite kia tika te whakahaere pāmahana e hiahiatia ana mō te whakatakotoranga kiriata angiangi kounga teitei, he mea nui tēnei mō te whakatutuki i te tipu rauemi ōrite. Tuarua, ka āwhina i te whakaiti i te mōrearea o te poke i roto i te taiao MBE mā te pupuri i te pono o te korehau. Hei whakamutunga,ngā paipa kua hipokina ki te korehauwhakapai ake i te whai huatanga whānui o te pūnaha MBE mā te whakaiti i te kohua o ngā wai cryogenic, ka iti ake ai ngā utu whakahaere me te roa ake o te ora o te pūnaha.
Te Anamata o ngā Paipa Korehau i roto i ngā Taupānga MBE
I te whanaketanga tonu o te hangarau MBE, me te tipu haere o ngā tono mō te tika ake,ngā paipa kua hipokina ki te korehauka nui haere te hiranga o tēnei mahi. Mā ngā mahi auaha i roto i ngā rauemi whakamahana me te hoahoa ka whakarei ake i te mahi a ēnei paipa, ka whakapai ake i te whai huatanga o te pūngao o ngā pūnaha MBE, ā, ka taea te hanga rauemi matatau ake. I te mea kei te haere tonu te whānui o ngā ahumahi pēnei i te hanga haurua-ira me te rorohiko irahiko, ko te hiahia mō ngā otinga whakahaere wera pono me te whai hua, pēnei i tengā paipa kua hipokina ki te korehau, ka tupu noa iho.
Hei whakamutunga,ngā paipa kua hipokina ki te korehauhe wāhanga nui ēnei i roto i te tukanga MBE, e āhei ai te whakahaere tika i te pāmahana me te whakarite kia angitu te whakatakoto i ngā kiriata angiangi kounga teitei. I te mea kei te piki haere tonu te hiahia mō ngā rauemi matatau, ka noho tonu ēnei paipa hei mea nui mō te pupuri i ngā taiao pāmahana iti e hiahiatia ana mō te hangarau MBE hou.
