Enhanced Thermoelectric Performance at the Superionic Phase Transitions of Mixed Ion-Electron Conducting Materials
The quality of a thermoelectric material is judged by the size of its temperature de- pendent thermoeletric-figure-of-merit (zT ). Superionic materials, particularly Zn<sub>4</sub>Sb<sub>3</sub> and Cu<sub>2</sub>Se, are of current interest for the high zT and low...
