Heavy-hole band splitting observed in mobility spectrum of p-type InAs grown on GaAs substrate
Jaroslaw Wrobel, Gilberto Umana-Membreno, Jacek Boguski +6
High quality berylium doped InAs layer grown by MBE on GaAs substrate has been examined via magnetotransport measurements and high resolution quantitative mobility spectrum analysi…
Nonlocal resistance and its fluctuations in microstructures of band-inverted HgTe/(Hg,Cd)Te quantum wells
G. Grabecki, J. Wróbel, M. Czapkiewicz +10
We investigate experimentally transport in gated microsctructures containing a band-inverted HgTe/Hg_{0.3}Cd_{0.7}Te quantum well. Measurements of nonlocal resistances using many c…
Transport in T-shaped ballistic junction
M. Bek, B. R. Bułka, J. Wróbel
We present studies of ballistic transport in three terminal T-shaped junction in a linear and non-linear regime. The floating electrode acts as a scatterer and modifies the conduct…
Absence of nonlocal resistance in microstructures of PbTe quantum wells
K. A. Kolwas, G. Grabecki, S. Trushkin +6
We report on experiments allowing to set an upper limit on the magnitude of the spin Hall effect and the conductance by edge channels in quantum wells of PbTe embedded between PbEu…
Contact superconductivity in In-PbTe junctions
G. Grabecki, K. A. Kolwas, J. Wrobel +7
The authors report on electron transport studies on superconductor-semiconductor hybrid structures of indium and n-type lead telluride, either in the form of quantum wells or bulk…
0.7-anomaly and magnetotransport of disordered quantum wires
M. Czapkiewicz, P. Zagrajek, J. Wrobel +6
The unexpected "0.7" plateau of conductance quantisation is usually observed for ballistic one-dimensional devices. In this work we study a quasi-ballistic quantum wire, for which…
