| Popis: | The fundamental principles of a selfconsistent thermodynamic approach to a simultaneous calculation of the entire set of basic thermodynamic functions of an elementary nonmagnetic metal, taking into account the thermal phonon anharmonicity and the concomitant Debye temperature θ dependence, are reported. It is shown that given a step-by-step analysis, the Debye temperature includes not only lattice but also electronic parameters, which could be interpreted as an indirect thermodynamic evidence of electron-phonon interaction in metals. The model adequacy, both in terms of its quantitative and qualitative validity, is shown by the example of aluminum. |
