544.22The 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 stepby-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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
