Nonlocal edge state transport in the quantum spin Hall state
Andreas Roth, Christoph Bruene, Hartmut Buhmann +4
We present direct experimental evidence for nonlocal transport in HgTe quantum wells in the quantum spin Hall regime, in the absence of any external magnetic field. The data conclu…
Lateral magnetic anisotropy superlattice out of a single (Ga,Mn)As layer
R. G. Dengel, C. Gould, J. Wenisch +3
We use lithographically induced strain relaxation to periodically modulate the magnetic anisotropy in a single (Ga,Mn)As layer. This results in a lateral magnetoresistance device w…
Fermi-edge Singularity in II-VI Semiconductor Resonant Tunneling Structures
M. Rueth, T. Slobodskyy, C. Gould +2
We report on the observation of Fermi edge enhanced resonant tunneling transport in a II-VI semiconductor heterostructure. The resonant transport through a self assembled CdSe quan…
