Valley filter from magneto-tunneling between single and bi-layer graphene
L Pratley, U. Zuelicke
We consider tunneling transport between two parallel graphene sheets where one is a single-layer sample and the other one a bilayer. In the presence of an in-plane magnetic field,…
Neutral edge modes in a superconductor -- topological-insulator hybrid structure in a perpendicular magnetic field
Rakesh P. Tiwari, U. Zülicke, C. Bruder +1
We study the low-energy edge states of a superconductor -- 3D topological-insulator hybrid structure (NS junction) in the presence of a perpendicular magnetic field. The hybridizat…
Magneto-tunnelling spectroscopy of chiral two-dimensional electron systems
L. Pratley, U. Zuelicke
We present a theoretical study of momentum-resolved tunneling between parallel two-dimensional conductors whose charge carriers have a (pseudo-)spin-1/2 degree of freedom that is s…
Suppression of Coulomb exchange energy in quasi-two-dimensional hole systems
T. Kernreiter, M. Governale, R. Winkler +1
We have calculated the exchange-energy contribution to the total energy of quasi-two-dimensional hole systems realized by a hard-wall quantum-well confinement of valence-band state…
Anisotropic Zeeman splitting in p-type GaAs quantum point contacts
Y. Komijani, M. Csontos, I. Shorubalko +5
Low-temperature electrical conductance spectroscopy measurements of quantum point contacts implemented in p-type GaAs/AlGaAs heterostructures are used to study the Zeeman splitting…
