## Abstract

The probability density of electrons in self-assembled InAs quantum dots is investigated by tunneling magnetocapacitance-voltage spectroscopy. A magnetic field in the plane of the tunneling layer is used to shift the momentum of the electrons tunneling into the dots and this way map the wave functions in k-space. When an additional perpendicular magnetic field is applied, a clear modification of the shape of the "p-state" wave functions is observed. In particular, the p^{+}-state changes from x, y-symmetry with a node along one crystal orientation to an almost circularly symmetric shape when the perpendicular magnetic field is increased from 0 to 9 T.
