Magnetic-field-induced modification of the wave-functions in InAs quantum dots

Lei, Wen; Wibbelhoff, O; Notthoff, C; Marquardt, B; Reuter, D; Wieck, A D; Lorke, A


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,...[Show more]
