J.open accessCopyright © 1995 American Physical Society428.8We present calculations of the temperature dependence of the lifetime of phonons due to anharmonic interactions. The contributions to the lifetime arising from phonon decay and phonon-phonon collisions are considered separately and, in addition, the relative strength of normal and umklapp processes is determined. The calculations are performed for an fcc lattice with nearest-neighbor central forces.American Physical Society1995-02-01engjournal articleVoRhttp://hdl.handle.net/2115/5929http://www.aps.org/https://doi.org/10.1103/PhysRevB.51.28570163-1829Physical Review B51528572863https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/5929/1/PRB51-5.pdfapplication/pdf1.31 MB1995-02-01
