TLDR
In this paper, the effect of Tl2Te3 on the transport properties of antimony and bismuth tellurides was studied and it was found that the addition of tl 2Te3 caused a lessening of the increase of hole concentration as low temperatures were approached, resulting in a slower decrease of the Seebeck coefficient.Abstract:
The effect on transport properties of the addition of 0.5-5% Tl2Te3 to p-type solid solutions of antimony and bismuth tellurides was studied. It was found that the addition of Tl2Te3 caused a lessening of the increase of hole concentration as low temperatures were approached, resulting in a slower decrease of the Seebeck coefficient with a decrease in temperature.read more
