Facile One‐Pot Solvothermal Synthesis of Bi2Te3 Nanoplate/Te Nanorod Composites with High Seebeck Coefficients for Flexible Film‐Based Thermoelectric Generators

Advanced Electronic Materials, EarlyView.
A one‐pot solvothermal reaction yields Bi2Te3 nanoplate/Te nanorod composites, in which the antimony precursor regulates crystallite size without lattice incorporation. Drop‐cast flexible films reach Seebeck coefficients of −127 and 323 µV K−1 at 393 K, and a flexible thermoelectric generator produces 6.2 mV at a temperature difference of 5.6 K ...
