Thermodynamic and Transport Properties of Crystals in Anharmonic Approximation

Abstract The thermodynamic and transport properties of the three‐dimensional body‐centred cubic lattice are investigated on the basis of the dynamical theory of anharmonic crystals. It is shown that the anharmonic effects of lattice vibrations are not negligible in calculations concerning the high‐temperature region. A comparison with experimental data is given for potassium theoretically described by various potential functions.
