Transport properties of quantum dot molecules and electronic structure of graphene quantum dot qubits
… molecule (TQDM) resulting from electron coherent tunneling between quantum dots is revealed. The spectra of electrical conductance of TQDM with charge filling from one to six electrons clearly depict the many-body and topological effects. The calculated charge stability diagram for conductance and …

Elektronischer Transport in Graphen
… “Dirac fermions”. Beside exotic effects like “Klein tunneling” an unconventional quantum Hall effect (QHE) can be observed with a Hall conductance quantized in units of 2e^2/h, 6e^2/h, 10e^2/h, 14e^2/h… . As a starting point for in-depth transport measurements the processing of graphene field …

Quantum transport in graphene heterostructures
… perfectly, a solid state analog of the Klein tunneling of relativistic quantum mechanics. The second part of the work describes the development of hexagonal boron nitride (hBN), an insulating isomorph of graphite, as a substrate and gate dielectric for graphene electronics. We use the …

Topological Insulating States in Photonics and Acoustics
… of all, pseudo spin and valley dependent one-way Klein tunneling is observed in the photonic platform. In addition, the one-way propagating edge states coexist with the bulk continuum which has opposite pseudo spin polarization compared to the states of edge. These exotic phenomena offer new ways …
