Fa'atinoga
O le TIG-BiTe-P/N-2 thermoelectric ingot o loʻo tupu faʻatasi ma le faʻaogaina o le Bi, Sb, Te, Se, doping faʻapitoa ma a tatou faiga faʻamaʻi faʻapitoa.O le Bi2Te3-faʻavae thermoelectric ingot ua faʻatupuina faʻapitoa ma sili ona lelei mo le faʻaogaina o mea faʻaogaina o le thermoelectric e faʻaaogaina mo le faʻaliliuina o le vevela mai le 100 ℃ (373K) i le 350 ℃ (623K) i le eletise.E masani lava, o le averesi fuainumera o agavaa ZT o tatou p-ituaiga ma n-ituaiga ingots i luga o le vevela laina 300K i le 600K e sili atu nai lo 0.7.O le module e faia i ia ingots e mafai ona ausia le 5% le lelei ma le 250 ℃ Delta T. I le taimi nei, o loʻo faʻaalia le matou ingot i le malosi faʻainisinia lelei ma le faʻamautuina o meatotino, e tuʻuina atu ai le maa autu mo le gaosia o le maualuga o le faʻatinoina ma le faʻalagolagoina o le gaosiga o le eletise.
