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…
Measurement of the energy dependence of phase relaxation by single electron tunneling
P. König, J. Könemann, T. Schmidt +3
Single electron tunneling through a single impurity level is used to probe the fluctuations of the local density of states in the emitter. The energy dependence of quasi-particle r…
Resonant tunneling through zero-dimensional impurity states: Effects of a finite temperature
P. König, U. Zeitler, J. Könemann +2
We have performed temperature dependent tunneling experiments through a single impurity in an asymmetric vertical double barrier tunneling structure. In particular in the charging…
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…
Spectroscopy of Local Density of States Fluctuations in a Disordered Conductor (Experiment)
T. Schmidt, R. J. Haug, V. I. Fal'ko +3
The local density of states of a degenerate semiconductor is investigated at low magnetic fields. In order to realize this experiment, we designed a strongly asymmetric double-barr…
