Nonmonotonous classical magneto-conductivity of a two-dimensional electron gas in a disordered array of obstacles
N. H. Siboni, J. Schluck, K. Pierz +4
Magnetotransport measurements in combination with molecular dynamics (MD) simulations on two-dimensional disordered Lorentz gases in the classical regime are reported. In quantitat…
Commensurability resonances in two-dimensional magneto-electric lateral superlattices
J. Schluck, S. Fasbender, T. Heinzel +4
Hybrid lateral superlattices composed of a square array of antidots and a periodic one-dimensional magnetic modulation are prepared in heterostructures. The two…
Interdependence of electroformation and hydrogen incorporation in titanium dioxide
M. Strungaru, M. Cerchez, S. Herbertz +3
It is shown that in nanoporous titanium dioxide films, sensitivity to atmospheric hydrogen exposure and electroforming can coexist and are interdependent. The devices work as conve…
Observation of quantum states without a semiclassical equivalence bound by a magnetic field gradient
B. Schüler, M. Cerchez, Hengyi Xu +4
Resonant transmission through electronic quantum states that exist at the zero points of a magnetic field gradient inside a ballistic quantum wire is reported. Since the semiclassi…
Impurity and edge roughness scattering in armchair graphene nanoribbons: Boltzmann approach
Hengyi Xu, Thomas Heinzel
The conductivity of armchair graphene nanoribbons in the presence of short-range impurities and edge roughness is studied theoretically using the Boltzmann transport equation for q…
Geometric magnetoconductance dips by edge roughness in graphene nanoribbons
Hengyi Xu, T. Heinzel, I. V. Zozoulenko
The magnetoconductance of graphene nanoribbons with rough zigzag and armchair edges is studied by numerical simulations. nanoribbons with sufficiently small bulk disorder show a pr…
