Enhanced spin-orbit scattering length in narrow Al_xGa_{1-x}N/GaN wires
P. Lehnen, Th. Schapers, N. Kaluza +2
The magnetotransport in a set of identical parallel AlGaN/GaN quantum wire structures was investigated. The width of the wires was ranging between 1110 nm and 340 nm. For all sets…
Andreev reflection and strongly enhanced magnetoresistance oscillations in GaInAs/InP heterostructures with superconducting contacts
I. E. Batov, Th. Schapers, N. M. Chtchelkatchev +2
We study the magnetotransport in small hybrid junctions formed by high-mobility GaInAs/InP heterostructures coupled to superconducting (S) and normal metal (N) terminals. Highly tr…
Longitudinal photocurrent spectroscopy of a single GaAs/AlGaAs v-groove quantum wire
N. I. Cade, M. Hadjipanayi, R. Roshan +5
Modulation-doped GaAs v-groove quantum wires (QWRs) have been fabricated with novel electrical contacts made to two-dimensional electron-gas (2DEG) reservoirs. Here, we present lon…
Coherent "metallic" resistance and medium localisation in a disordered 1D insulator
Martin Mosko, Pavel Vagner, Michal Bajdich +1
It is believed, that a disordered one-dimensional (1D) wire with coherent electronic conduction is an insulator with the mean resistance <ρ> \simeq e^{2L/ξ} and resistance dispersi…
