โœฆ Synopsis

A calculation of the basal plane thermal conductivity of graphite with no adjustable parameters is presented. The graphite crysta! is treated as a set of noninteracting two-dimensional lattices and only in-plane vibrations are considered. The rtlaxalion time is determined through the diagonal matrix elements of the scattering matrix. The anharmonicity coefficients are obtained from the thermodynamic equation of state with the use of the experimental data for the thermal expansion coefficient. The results are in qualitative agreement with the experiments. This calculation permits in principle to analvze separately the contributions nf the various branches and phonons to the heat transfek and to the scattering.
