Experimental determination of Rashba and Dresselhaus parameters and -factor anisotropy via Shubnikov-de Haas oscillations
F. Herzog, H. Hardtdegen, Th. Schaepers +2
The spin splitting of conduction band electrons in inversion-asymmetric InGaAs/InP quantum wells is studied by Shubnikov-de Haas measurements combining the analysis of beating patt…
Scanning tunneling microscopy with InAs nanowire tips
Kilian Flöhr, Kamil Sladek, H. Yusuf Günel +5
Indium arsenide nanowires grown by selective-area vapor phase epitaxy are used as tips for scanning tunneling microscopy (STM). The STM tips are realized by positioning the wires m…
Weak antilocalization in high mobility Ga(x)In(1-x)As/InP two-dimensional electron gases with strong spin-orbit coupling
Vitaliy A. Guzenko, Thomas Schäpers, Hilde Hardtdegen
We have studied the spin-orbit interaction in a high mobility two-dimensional electron gas in a GaInAs/InP heterostructure as a function of an applied gate voltage as well as a fun…
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…
