Mahi

Ko te TIG-BiTe-P/N-2 thermoelectric ingot kua whakatipuhia me te koranu o Bi, Sb, Te, Se, doping motuhake me o tatou tukanga whakakoiata ahurei. Ko te ingot thermoelectric-a-Bi2Te3 he mea whakatipu motuhake me te arotau mo te hanga i nga waahanga thermoelectric i whakamahia hei huri i te puna wera mai i te 100 ℃(373K) ki te 350 ℃(623K) ki te hiko. Ko te tikanga, ko te ahua toharite o te kaiaka ZT o a maatau momo momo-p me nga momo-n i runga i te awhe pāmahana 300K ki te 600K he nui ake i te 0.7. Ka taea e te kōwae i hangaia me nga ingots penei te 5% te pai me te 250 ℃ Delta T. I tenei wa, kei te whakaatuhia to tatou ingot me te kaha o te miihini pai me te taonga tino pumau, e whakarato ana i te kohatu matua mo te whakaputa i nga mahi teitei me nga waahanga whakangao hiko pono.
