He Whakarāpopototanga mō te Epitaxy Rīpene Irahiko (MBE)
I whakawhanakehia te hangarau o te Molecular Beam Epitaxy (MBE) i ngā tau 1950 hei whakarite i ngā rauemi kiriata angiangi haurua-waenga mā te whakamahi i te hangarau mimiti korehau. Nā te whanaketanga o te hangarau korehau tino-tiketike, kua whānuitia te whakamahinga o te hangarau ki te ao pūtaiao haurua-waenga.
Ko te hihiri o te rangahau rauemi haurua-ira ko te hiahia mō ngā taputapu hou, ka pai ake pea te mahi a te pūnaha. Hei tāpiri, ka taea e ngā hangarau rauemi hou te whakaputa taputapu hou me ngā hangarau hou. Ko te epitaxy hihi ngota (MBE) he hangarau korehau teitei mō te tipu o te paparanga epitaxial (te nuinga o te wā he haurua-ira). Ka whakamahia e ia te hihi wera o ngā ngota pūtake, o ngā ngota rānei e pā ana ki te papa tioata kotahi. Ko ngā āhuatanga korehau tino teitei o te tukanga ka taea te whakarewa me te tipu o ngā rauemi whakamarumaru i runga i ngā mata haurua-ira hou kua tipu, ka hua ake he atanga kore-parahanga.
Hangarau MBE
I mahia te epitaxy hihi ngota i roto i te korehau teitei, i te korehau tino-teitei rānei (1 x 10-8Taiao Pa). Ko te āhuatanga tino nui o te epitaxy hihi ngota ko tōna tere whakatakotoranga iti, e āhei ai te kiriata ki te tipu epitaxial i te tere iti iho i te 3000 nm ia hāora. Ko te tere whakatakotoranga iti nei me nui te korehau hei whakatutuki i te taumata ma rite ki ētahi atu tikanga whakatakotoranga.
Hei whakatutuki i te korehau tino teitei kua whakaahuatia i runga ake nei, he paparanga whakamatao kei te taputapu MBE (pūtau Knudsen), ā, me pupuri tonu te taiao korehau tino teitei o te rūma tipu mā te whakamahi i tētahi pūnaha tohanga hauota wai. Ka whakamatao te hauota wai i te pāmahana o roto o te taputapu ki te 77 Kelvin (−196 °C). Ka taea e te taiao pāmahana iti te whakaiti ake i te nui o ngā poke i roto i te korehau, ā, ka pai ake te whakatakotoranga o ngā kiriata angiangi. Nō reira, me whai pūnaha tohanga whakamatao hauota wai motuhake kia taea ai e ngā taputapu MBE te whakarato i tētahi putunga hauota wai -196 °C tonu me te pumau.
Pūnaha Whakawhitinga Whakamatao Hauota Wai
Ko te pūnaha tohanga hauota wai korehau te nuinga o te wā,
● tāke waikura
● paipa matua me te peka kua hipokina ki te korehau / ngongo kua hipokina ki te korehau
● Te wehewehe wāhanga motuhake a MBE me te paipa whakaputa hau kua hipokina ki te korehau
● ngā takirere kua hipokina ki te korehau
● ārai hau-wai
● tātari hipoki korehau
● pūnaha papu korehau hihiri
● Pūnaha whakamatao me te whakamahana anō i mua i te whakamahana
Kua kite te Kamupene Taputapu Cryogenic HL i te hiahia mō te pūnaha whakamatao hauota wai MBE, ā, kua whakaritea te pou tuara hangarau hei whakawhanake angitu i tētahi pūnaha whakamatao hauota wai MBE motuhake mō te hangarau MBE, me tētahi huinga katoa o ngā ārai korehau.edpūnaha paipa, kua whakamahia i roto i te maha o ngā umanga, ngā whare wānanga me ngā whare rangahau.
Taputapu Cryogenic HL
I whakatūria a HL Cryogenic Equipment i te tau 1992, ā, he waitohu e hono ana ki te Chengdu Holy Cryogenic Equipment Company i Haina. E whakapau kaha ana a HL Cryogenic Equipment ki te hoahoa me te hanga i te Pūnaha Paipa Cryogenic Insulated Teitei me ngā Taputapu Tautoko e pā ana.
