Popis: | The nonequilibrium phonon number dynamics of three-phonon processes are studied for 1/ f current fluctuation in solid-state materials. It is shown that the excitation of a nonequilibrium acoustic phonon diffuses to thermalize in a wave-number space with a t -1/2 long-time tail when the excited phonon interacts with a thermal phonon of nearly zero wave number. |
