Waxqabadka

Tig-BiTe-P/N-2 heerkulbeeg-ku-dhalatada waxa lagu beeraa daawaynta Bi, Sb, Te, Se, doping-ga gaarka ah iyo hababkayada kirismaska ​​ah ee gaarka ah.Heerkulbeegga ku salaysan Bi2Te3 si gaar ah ayaa loo koray waxaana loo habeeyay samaynta qalabka korantada ee loo isticmaali jiray beddelka kulaylka u dhexeeya 100 ℃ (373K) ilaa 350 ℃(623K) koronto.Guud ahaan, celceliska jaantuska mudnaanta ZT ee nooca p-nooca iyo nooca n-ku-darka ka sarreeya heerkulka u dhexeeya 300K ilaa 600K wuu ka weyn yahay 0.7.Module-ka lagu sameeyay ingots-ka noocan oo kale ah wuxuu gaari karaa 5% waxtarka leh 250 ℃ Delta T. Dhanka kale, ingot our waxaa lagu soo bandhigay xoog farsamo wanaagsan iyo hanti aad u xasilloon, bixinta dhagaxa muhiimka ah ee soo saarista waxqabadka sare iyo modules koronto la isku halayn karo.
