Electric transport through circular graphene quantum dots: Presence of disorder
G. Pal, W. Apel, L. Schweitzer
The electronic states of an electrostatically confined cylindrical graphene quantum dot and the electric transport through this device are studied theoretically within the continuu…
Disorder-driven splitting of the conductance peak at the Dirac point in graphene
L. Schweitzer, P. Markos
The electronic properties of a bricklayer model, which shares the same topology as the hexagonal lattice of graphene, are investigated numerically. We study the influence of random…
Levitation of quantum Hall critical states in a lattice model with spatially correlated disorder
Th. Koschny, L. Schweitzer
The fate of the current carrying states of a quantum Hall system is considered in the situation when the disorder strength is increased and the transition from the quantum Hall liq…
Floating of critical states and the QH to insulator transition
H. Potempa, L. Schweitzer
The transition from the quantum Hall state to the insulator is considered for non-interacting electrons in a two-dimensional disordered lattice model with perpendicular magnetic fi…
Levitation of Current Carrying States in the Lattice Model for the Integer Quantum Hall Effect
Th. Koschny, H. Potempa, L. Schweitzer
The disorder driven quantum Hall to insulator transition is investigated for a two-dimensional lattice model. The Hall conductivity and the localization length are calculated numer…
