Optical and electronic properties of thermoelectric Zn4 Sb3 across the low-temperature phase transitions
Research output: Contribution to journal › Article
Using infrared reflection spectroscopy the authors show that the phase transitions from disordered high temperature Β- Zn4 Sb3 into the increasingly higher ordered and complex structured low-temperature phases α and α′ are accompanied by a significant increase in the free charge carrier density and a concomitant increase of the effective scattering rate.
