Ukusebenza

I-TIG-BiTe-P/N-2 ingot ye-thermoelectric ikhuliswe nge-alloy ye-Bi, Sb, Te, Se, i-doping ekhethekileyo kunye neenkqubo zethu ezikhethekileyo ze-crystallizing. I-Bi2Te3-based thermoelectric ingot ikhuliswe ngokukodwa kwaye ilungiselelwe ukwenza iimodyuli ze-thermoelectric ezisetyenziselwa ukuguqula umthombo wobushushu ukusuka kwi-100℃(373K) ukuya kwi-350℃(623K) ibe ngumbane. Ngokubanzi, umndilili womyinge we-ZT wodidi lwethu lwe-p kunye nohlobo lwe-n-ingots ngaphezulu koluhlu lobushushu obuphakathi kwe-300K ukuya kwi-600K likhulu kuno-0.7. Imodyuli eyenziwe ngama-ingots anjalo inokufezekisa ukusebenza kwe-5% kunye ne-250 ℃ Delta T. Okwangoku, i-ingot yethu ibonakaliswe ngamandla omatshini kunye nepropati ezinzileyo kakhulu, ukubonelela ngelitye eliphambili lokuvelisa ukusebenza okuphezulu kunye neemodyuli ezithembekileyo zokuvelisa amandla.
