Abstract
It is shown that the high-temperature behavior of the lattice thermal conductivity of silicon, which has been carefully remeasured recently by Fulkerson et al., can be explained by the four-phonon processes. It has been also found that the major contribution to the phonon thermal conductivity at high temperatures comes from the high-frequency transverse phonons.Keywords
