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 ebangeni 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 iboniswa ngamandla omshini omuhle kanye nempahla ezinzile, ehlinzeka ngetshe eliyinhloko lokukhiqiza ukusebenza okuphezulu kanye namamojula okukhiqiza amandla athembekile.

Isicelo

Ukwakha i-P/N junction, esetshenziswa kusiqandisi se-semiconductor, isizukulwane sempushana kagesi eshisayo njll.

Izinzuzo Zethu

I-Rare-earth-scandium-oxide-inenani-elihle-2

Isevisi esingayinikeza

1) Inkontileka esemthethweni ingasayinwa

2) Isivumelwano sokugcinwa kuyimfihlo singasayinwa

3) Isiqinisekiso sokubuyiselwa imali sezinsuku eziyisikhombisa

Okubaluleke nakakhulu: asikwazi ukunikeza umkhiqizo kuphela, kodwa isevisi yesixazululo sobuchwepheshe!
