Low temperature thermoelectric properties of melt spun Bi85Sb15 alloys
TL;DR: In this article, the effects of cooling rate in MS process on the microstructure and low temperature thermoelectric properties (10 − 300 K) of bulk Bi 85 Sb 15 have been systematically investigated, with increasing the cooling rate, the increase of constituents homogeneity and corresponding increase in actual energy gap give rise to a significant improvement of electron mobility and decrease in electron concentration.
