Positive Terahertz Photoconductivity in CdHgTe Under Hydrostatic Pressure
Ivan Yahniuk, Dmitriy A. Kozlov, Mariya D. Moldavskaya +10
Positive terahertz photoconductivity is observed at room temperature in CdHgTe thin films with different Cd contents. We show that electron gas heating caused by Drude-like absorpt…
Massless Dirac fermions in III-V semiconductor quantum wells
S. S. Krishtopenko, W. Desrat, K. E. Spirin +12
We report on the clear evidence of massless Dirac fermions in two-dimensional system based on III-V semiconductors. Using a gated Hall bar made on a three-layer InAs/GaSb/InAs quan…
Temperature-induced topological phase transition in HgTe quantum wells
A. M. Kadykov, S. S. Krishtopenko, B. Jouault +9
We report a direct observation of temperature-induced topological phase transition between trivial and topological insulator in HgTe quantum well. By using a gated Hall bar device,…
Pressure and temperature driven phase transitions in HgTe quantum wells
S. S. Krishtopenko, I. Yahniuk, D. B. But +3
We present theoretical investigations of pressure and temperature driven phase transitions in HgTe quantum wells grown on CdTe buffer. Using the 8-band \textbf{kp} Hamiltoni…
Phase transitions in two tunnel-coupled HgTe quantum wells. Bilayer graphene analogy and beyond
S. S. Krishtopenko, W. Knap, F. Teppe
HgTe quantum wells possess remarkable physical properties as for instance the quantum spin Hall state and the 'single-valley' analog of graphene, depending on their layer thickness…
Room Temperature Coherent and Voltage Tunable Terahertz Emission from Nanometer-Sized Field Effect Transistors
S. Boubanga-Tombet, F. Teppe, J. Torres +14
We report on reflective electro-optic sampling measurements of TeraHertz emission from nanometer-gate-length InGaAs-based high electron mobility transistors. The room temperature c…
