Bixinta teernary-ternary bismuth tellurideP-nooca Bi0.5Sb1.5Te3iyoN-nooca Bi2Te2.7Se0.3
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 ayaa si gaar ah loo koray waxaana loo habeeyay samaynta qalabka kuleyliyaha 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% hufnaan leh 250 ℃ Delta T. Dhanka kale, ingot-kayaga waxaa lagu soo bandhigay awood farsamo oo wanaagsan iyo hanti aad u deggan, siinta dhagaxa muhiimka ah ee soo saarista waxqabadka sare iyo modules-koronto la isku halayn karo.
