Weak antilocalization in HgTe quantum wells near a topological transition
(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2010)
The anomalous alternating magnetoresistivity in HgTe quantum wells with thicknesses of 5.8 and 8.3 nm, i.e., near the transition from the direct band spectrum to an inverted spectrum, has been revealed and analyzed. It has ...
Robust edge states induced by electron-phonon interaction in graphene nanoribbons
(American Physical Society, 2018-07-17)
The search of new means of generating and controlling topological states of matter is at the front of many joint efforts, including band-gap engineering by doping and light-induced topological states. Most of our understading, ...

Two-dimensional semimetal-insulator transition in HgTe-based quantum wells induced by a longitudinal magnetic field
(MAIK NAUKA/INTERPERIODICA/SPRINGERNEW YORK, 2012)
A metal-insulator transition in a two-dimensional semimetal based on HgTe quantum wells is discovered. The transition is induced by a magnetic field applied parallel to the plane of the quantum well. The threshold behavior ...
Nonlocal Transport Near Charge Neutrality Point in a Two-Dimensional Electron-Hole System
(AMER PHYSICAL SOCCOLLEGE PK, 2012)
Nonlocal resistance is studied in a two-dimensional system with a simultaneous presence of electrons and holes in a 20 nm HgTe quantum well. A large nonlocal electric response is found near the charge neutrality point in ...
Helical edge states in multiple topological mass domains
(Institute of Physics - IOPBristol, 2012-12)
The two-dimensional topological insulating phase has been experimentally discovered in HgTe quantum wells. The low-energy physics of two-dimensional topological insulators (TIs) is described by the Bernevig-Hughes-Zhang ...
