Quantum-coherent transport in low-dimensional mesoscopic structures and thin films
… from the amplitudes of the quantum-mechanical Aharonov-Bohm oscillations. The side gates allow for an in-plane controllable electric field. Asymmetrically biased side-gate voltages allow for the breaking of the two-dimensional parity symmetry of the ring device, effectively resulting in reduced …

Phase coherent transport phenomena in HgTe quantum well structures
… e.g., a ring shaped structure to investigate the Aharonov-Bohm and related effects. Due to the fact, that all experiments, described in this thesis, were performed on Hg-based samples, the exceptional position of such samples among the “classical” semiconductors has been clarified. Hg1-xMnx Te …

Mesoscopic quantum interference experiments in InGaAs and GaAs two-dimensional systems
… The single ring interferometer yields pronounced Aharonov-Bohm (AB) oscillations with magnetic flux periodicity of h/e over a wide range of magnetic field. The periodicity was confirmed by Fourier transformation of the oscillations. The AB oscillation amplitude shows a quasi-periodic modulation …
