Quantitative theory of backscattering in topological HgTe and (Hg,Mn)Te quantum wells: acceptor states, Kondo effect, precessional dephasing, and bound magnetic polaron
Tomasz Dietl
We present the theory and numerical evaluations of the backscattering rate determined by acceptor holes or Mn spins in HgTe and (Hg,Mn)Te quantum wells in the quantum spin Hall reg…
Effects of charge dopants in quantum spin Hall materials
Tomasz Dietl
Semiconductors' sensitivity to electrostatic gating and doping accounts for their widespread use in information communication and new energy technologies. It is demonstrated quanti…
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)…
Superexchange dominates in magnetic topological insulators
Cezary Sliwa, Carmine Autieri, Jacek A. Majewski +1
It has been suggested that the enlarged spin susceptibility in topological insulators, described by Van Vleck's formalism, accounts for the ferromagnetism of bismuth-antimony topol…
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…
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…
