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…
Ising Quantum Hall Ferromagnet in Magnetically Doped Quantum Wells
J. Jaroszynski, T. Andrearczyk, G. Karczewski +7
We report on the observation of the Ising quantum Hall ferromagnet with Curie temperature as high as 2 K in a modulation-doped (Cd,Mn)Te heterostructure. In this system field…
Quantum ballistic transport in constrictions of n-PbTe
G. Grabecki, J. Wrobel, T. Dietl +7
Conductance of submicron constrictions of PbTe:Bi was studied up to 8T and between 4.2K and 50mK. The structures were fabricated by electron beam lithography and chemical etching o…
