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…

Double Exchange in Electron Doped Ca1-xYxMnO3 Manganites
H. Aliaga, M. T. Causa, A. Butera +6
We have studied structural, magnetic and transport properties as a function of temperature and magnetic field in the electron doped manganite YxCa1-xMnO3, for 0<x<0.25. We found th…

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…
