Abstract:
Direct measurement of the energy dependence of the inelastic decay rate τ(E) of a quasiparticle state in a disordered conductor was performed using resonant tunneling spectroscopy. Decay rate was obtained from the analysis of the magnitude of disorder-induced fluctuations in the local density of states. Quantitative comparison with the standard theory was achieved.
