Signatures of hydrodynamic flow of topological carriers in SnTe multi-terminal nanowires
Dawid Śnieżek, Cezary Śliwa, Krzysztof Dybko +5
In this work, we used 20 nm thick CdTe/SnTe/CdTe [001] quantum wells to make 6- and 8-terminal nano-structures with the etched cross-junctions of sub-micron width with walls direct…
Perspectives of HgTe Topological Insulators for Quantum Hall Metrology
Ivan Yahniuk, Sergey S. Krishtopenko, Grzegorz Grabecki +16
We report the studies of high-quality HgTe/(Cd,Hg)Te quantum wells (QWs) with a width close to the critical one , corresponding to the topological phase transition and graphen…
Conductance resonances and crossing of the edge channels in the quantum Hall ferromagnet state of Cd(Mn)Te microstructures
E. Bobko, D. Płoch, D. Śnieżek +6
In this paper we report on the observation of very high and narrow magnetoconductance peaks which we attribute to the transition to quantum Hall ferromagnet (QHFM) state occurring…
Conductance oscillations in quantum point contacts of InAs/GaSb heterostructures
Michał Papaj, Łukasz Cywiński, Jerzy Wróbel +1
We study quantum point contacts in two-dimensional topological insulators by means of quantum transport simulations for InAs/GaSb heterostructures and HgTe/(Hg,Cd)Te quantum wells.…
An Intermediate Phase at the Metal-Insulator Boundary in a Magnetically Doped Two-Dimensional Electron System
J. Jaroszynski, T. Andrearczyk, G. Karczewski +4
A magnetotransport study in magnetically doped (Cd,Mn)Te 2D quantum wells reveals an apparent metal-insulator transition as well as an anomalous intermediate phase just on its meta…
Effect of bulk inversion asymmetry on the Datta-Das transistor
A. Łusakowski, J. Wróbel, T. Dietl
A model of the Datta-Das spin field-effect transistor is presented which, in addition to the Rashba interaction, takes into account the influence of bulk inversion asymmetry of zin…
Magnetoconductance noise and irreversibilities in submicron wires of spin-glass n-CdMnTe
J. Jaroszynski, J. Wrobel, G. Karczewski +2
Signatures of spin-glass freezing such as the appearance of 1/f conductance noise, the recovery of universal conductance fluctuations, aging, as well as magnetic and thermal irreve…
