Quantum Size Effect in Optically Active Indium Selenide Crystal Phase Heterostructures Grown by Molecular Beam Epitaxy
Piotr Wojnar, Maciej Wojcik, Piotr Baranowski +9
Indium selenide attracts the interest due to its outstanding electronic and optical properties which are potentially prospective in view of applications in electronic and photonic…
Signatures of dephasing by mirror-symmetry breaking in weak-antilocalization magnetoresistance across the topological transition in PbSnSe
Alexander Kazakov, Wojciech Brzezicki, Timo Hyart +12
Many conductors, including recently studied Dirac materials, show saturation of coherence length on decreasing temperature. This surprising phenomenon is assigned to external noise…
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…
Disorder suppression and precise conductance quantization in constrictions of PbTe quantum wells
G. Grabecki, J. Wrobel, T. Dietl +7
Conductance quantization was measured in submicron constrictions of PbTe, patterned into narrow,12 nm wide quantum wells deposited between PbEuTe barriers. Becaus…
Unidirectional Transmission of Electrons in a Magnetic Field Gradient
G. Grabecki, J. Wrobel, K. Fronc +7
The work presents an experimental demonstration of time-reversal asymmetry of electron states propagating along boundary separating areas with opposite magnetic fields. For this pu…
