“…Thus, one can conclude that the pressure dependence of the thermopower is highly anisotropic depending on the crystallographic orientation for p-type Bi1.8Sb0.2Te3.0. The increase in the thermopower with pressure may be associated with the change in the electronic band structure which has a major impact on transport properties [13][14].…”

The pressure eﬀect on the thermopower has been investigated for the Bi1.8Sb0.2Te3.0 alloys. We have found an anisotropic pressure dependence on the thermopower for p- and n-type Bi1.8Sb0.2Te3.0 at room temperature. Along a-axis, for p-type, the thermopower value increased with increase of pressure at a rate of 13.9 %/Gpa, whereas, along c-axis, itkeeps approximately constant.. The absolue value of the thermopower decreased with pressure along both a- and c-axis for n-type. The power factor increased largely with increase of pressure for p-type Bi1.8Sb0.2Te3.0, while it is approximately constant for n-type.

The thermoelectric power, electrical conductivity, crystal structure, and Raman active phonon modes of the semiconductor β-K2Bi8Se13 have been studied under pressure. There is a large increase in the electrical conductivity in the pressure range 0–1 GPa and a sharp maximum in the magnitude of the thermoelectric power at ∼1.4 GPa. X-ray diffraction studies revealed no structural change upon compression. The Raman active vibrational modes did not shift substantially with pressure, suggesting that the pressure induced changes in the phonon thermal conductivity may not be large. The thermoelectric figure of merit, ZT, likely increases by a factor of at least 2 from its ambient pressure value of 0.23. This is the first n-doped material for which we have observed a peak in the thermoelectric power suggestive of an electronic topological transition upon compression.
