Phonon Frequencies, Debye Temperature, Grüneisen Parameter and Transport Properties of Cesium

Abstract

Calculations of the phonon frequencies, temperature variation of Debye temperature, Grüneisen parameter, and electrical and thermal resistivities of cesium have been made using the modified form of our recent lattice dynamical model. An equilibrium condition, which preserves the crystal stability is obtained and incorporated with the model. The computed values are compared with the available theoretical and experimental data. Our theoretical results are in reasonably good agreement with the theoretical and experimental values.
