Correlation-function spectroscopy of inelastic lifetime in heavily doped GaAs heterostructures
J. Könemann, P. König, T. Schmidt +3
Measurements of resonant tunneling through a localized impurity state are used to probe fluctuations in the local density of states of heavily doped GaAs. The measured differential…

Spin Effects in the Local Density of States of GaAs
P. König, T. Schmidt, R. J. Haug
We present spin-resolved measurements of the local density of states in Si doped GaAs. Both spin components exhibit strong mesoscopic fluctuations. In the magnetic quantum limit, t…

Energy Dependence of Quasi-Particle Relaxation in a Disordered Fermi Liquid
T. Schmidt, P. König, E. McCann +2
A spectroscopic method is applied to measure the inelastic quasi-particle relaxation rate in a disordered Fermi liquid. The quasi-particle relaxation rate, is deduced from the…
