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…
