Ukusebenza
I-TIG-BiTe-P/N-2 ingot ye-thermoelectric ikhuliswa nge-alloy ye-Bi, Sb, Te, Se, i-doping ekhethekile kanye nezinqubo zethu eziyingqayizivele zokucwebezela.I-Bi2Te3-based thermoelectric ingot ikhuliswe ngokukhethekile futhi yalungiselelwa ukwenza amamojula we-thermoelectric asetshenziselwa ukuguqula umthombo wokushisa osuka ku-100℃(373K) ukuya ku-350℃(623K) ube ugesi.Ngokuvamile, isilinganiso sesilinganiso se-ZT sohlobo lwethu lwe-p kanye ne-n-type ingots phezu kwebanga lokushisa elingu-300K kuya ku-600K sikhulu kuno-0.7.Imojula eyenziwe ngama-ingots anjalo ingakwazi ukufeza ukusebenza kahle okungu-5% nge-250℃ Delta T. Phakathi naleso sikhathi, ingot yethu ifakwe ngamandla amahle omshini kanye nempahla ezinzile, ehlinzeka ngetshe eliyinhloko lokukhiqiza ukusebenza okuphezulu kanye namamojula okukhiqiza amandla athembekile.
