HgTe quantum wells for QHE metrology under soft cryomagnetic conditions: permanent magnets and liquid temperatures
I. Yahniuk, A. Kazakov, B. Jouault +11
HgTe quantum wells with a thickness of 7 nm may have a graphene-like band structure and have been recently proposed to be potential candidates for quantum Hall effect (QHE)…
Conductance spectra of (Nb, Pb, In)/NbP -- superconductor/Weyl semimetal junctions
G. Grabecki, A. Dąbrowski, P. Iwanowski +11
The possibility of inducing superconductivity in type-I Weyl semimetal through coupling its surface to a superconductor was investigated. A single crystal of NbP, grown by chemical…
Probing spatial extent of topological surface states by weak antilocalization experiments
K. Dybko, G. P. Mazur, W. Wolkanowicz +7
Weak antilocalization measurements has become a standard tool for studying quantum coherent transport in topological materials. It is often used to extract information about number…
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…
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…
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…
