Abstract
The widespread application of thermoelectric devices in cooling and waste heat recovery systems will be achieved when materials achieve high thermoelectric performance. However, improving thermoelectric performance is not straightforward because the Seebeck coefficient and electrical conductivity of the materials have opposite trends with varying carrier concentration. Here, we demonstrate that..... More

Abstract
In this study, we report the influence of Te vacancy formation on the thermoelectric properties of n-type Cu_0.008Bi₂Te_2.7Se_0.3 alloys, including their electronic and thermal transport properties. Te-deficient Cu_0.008Bi₂Te_2.7-xSe_0.3 (x = 0, 0.005, 0.01 and 0.02) samples were systematically synthesized and characterized. Regarding electronic transport properties, carrier concentration was increased with..... More
