Abstract

The relaxation of a nonequilibrium population in the presence of equilibrium carriers is a situation frequently encountered in devices. It is also interesting from the fundamental point of view since theoretical work1 has predicted the existence of weakly damped acoustic plasmons under nonequilibrium situations and their importance in accelerating the relaxation as well as a drastic dependence on the temperature of thermalized electrons existing in addition to a nonequilibrium electron-hole plasma. However, no experimental investigation of acoustic-plasmon effects in nonequilibrium plasmas has been performed up to now.
