5 Apr 2013 | Abstract: | The decay of the optical phonon into the two phonons of smaller energy is
calculated for Si nanocrystals. The rate of the process is in the range of 1 to
10 ps. Such anharmonic phonon decay may control the energy relaxation rate of
excited carriers in Si/SiO$_2$ nanocrystals. Relevance of the phonon decay to
the experimentally observed hot carrier photoluminescence is discussed. | Source: | arXiv, 1304.1623 | Services: | Forum | Review | PDF | Favorites |
