Comparison of high-temperature three-phonon resistivities from different theoretical models
We present a comparison of high-temperature three-phonon resistivities from the relaxation time methods due to Klemens, Callaway, and Debye, and the variational method due to Leibfried and Schlömann. All the calculations are based upon the same choice of anharmonic crystal potential; and hence the results are suitable for comparison on quantitative basis. We find that the resistivities in increasing order of magnitude come from the methods due to Klemens, Callaway Debye, and Leibfried and Schlömann respectively.
