Abstract

We report on a study of resonant tunneling in a magnetic field tilted with respect to the current direction on a double-barrier structure. A splitting of the resonant current peak into several satellites is observed and corresponds to tunneling with nonconservation of the Landau-level index. We propose a simple coherent-tunneling model that accounts very well for both positions and magnitudes of the observed features, and we show that these experiments clearly evidence new selection rules for tunneling in a tilted magnetic field.
