Mesoscopic fluctuations of the local density of states (LDOS) in a highly degenerate semiconductor are studied by single electron tunneling through a discrete localized state. A damping of the amplitude of the LDOS fluctuations with increasing voltage is observed. We attribute this damping to inelastic processes in the emitter. From this inelastic broadening of our spectrometer the quasi-particle relaxation is evaluated.
