Pressure-induced insulator-to-metal transitions for enhancing thermoelectric power factor in bismuth telluride-based alloys.
First-principles calculations revealing insulator-to-metal transitions in Bi2Te3 and Bi2Te2Se, at 9 GPa and 12.5 GPa, respectively, match with prior experiments. Our electronic band structure calculations and accompanying Boltzmann transport calculations of thermoelectric properties for Bi2-xSbxTe2-ySey alloys explain and predict large power factor changes induced by pressure. Complex band dege...

متن کاملThermoelectric Power Factor of Low Dimensional Silicon Nanowires
We analyze the thermoelectric power factor in ultra-narrow low-dimensional silicon nanowires (NWs) by employing atomistic considerations for the electronic structures and linearized Boltzmann transport theory. We consider different transport orientations and both n-type and p-type NWs. We show that the NW properties are highly anisotropic, especially for p-type, and as the diameter is reduced f...
متن کاملHigh thermoelectric performance in copper telluride
Recently, Cu2-δS and Cu2-δSe were reported to have an ultralow thermal conductivity and high thermoelectric figure of merit zT. Thus, as a member of the copper chalcogenide group, Cu2-δTe is expected to possess superior zTs because Te is less ionic and heavy. However, the zT value is low in the Cu2Te sintered using spark plasma sintering, which is typically used to fabricate high-density bulk s...
متن کاملElectrical conductivity and thermoelectric power of the compounds (
The electrical conductivity, U, and thermoelectric power, S , of the solid solutions (Dy,Y,-x)2M0207 have been measured in the temperature range 300-10 K. Log(aT) versus 1/T and S versus 1/T plots were found to be linear down to about 100 K. The activation energies E, and Es obtained from conductivity and thermoelectric power measurements, respectively, differ by one order of magnitude, indsati...
