Quantized magnetic confinement in quantum wires
A. Tarasov, S. Hugger, Hengyi Xu +6
Ballistic quantum wires are exposed to longitudinal profiles of perpendicular magnetic fields composed of a spike (magnetic barrier) and a homogeneous part. An asymmetric magnetoco…
Small scale lateral superlattices in two-dimensional electron gases prepared by diblock copolymer masks
S. Hugger, T. Heinzel, T. Thurn-Albrecht
A poly(styrene-block-methylmethacrylate) diblock copolymer in the hexagonal cylindrical phase has been used as a mask for preparing a periodic gate on top of a Ga[Al]As-heterostruc…
Magnetic barrier induced conductance fluctuations in quantum wires
S. Hugger, Hengyi Xu, A. Tarasov +5
Quasi-ballistic semiconductor quantum wires are exposed to localized perpendicular magnetic fields, also known as magnetic barriers. Pronounced, reproducible conductance fluctuatio…
Influence of magnetic field offsets on the resistance of magnetic barriers in two-dimensional electron gases
S. Hugger, M. Cerchez, H. Xu +1
Magnetic barriers in two-dimensional electron gases are shifted in B space by homogeneous, perpendicular magnetic fields. The magnetoresistance across the barrier shows a character…
Effect of edge transmission and elastic scattering on the resistance of magnetic barriers
M. Cerchez, S. Hugger, T. Heinzel +1
Strong magnetic barriers are defined in two-dimensional electron gases by magnetizing dysprosium ferromagnetic platelets on top of a Ga[Al]As heterostructure. A small resistance ac…
