From: Conductivity-limiting bipolar thermal conductivity in semiconductors
(a) The calculated electron wavelength and the product of the Fermi-Dirac distribution function and electronic density of states f(E) g(E) vs. energy with the zero point corresponding to the conduction band minimum (Ec). (b) The experimental and modeled bipolar thermal conductivity vs. temperature, for p-type zone melted (ZM) and nanostructured (MS-SPS) Bi0.5Sb1.5Te3. The inset is a TEM picture of the MS-SPS bulk sample which shows 10–50 nm nanoprecipitates. (The room temperature minority carrier mobilities of ZM and Nano samples are μn = 4095 and 1115 cm2/V-s, respectively).
