Strongly nonlinear Bernstein modes in graphene reveal plasmon-enhanced near-field magnetoabsorption
I. Yahniuk, I. A. Dmitriev, A. L. Shilov +12
Bernstein modes -- hybrid magnetoplasmon excitations arising from the coupling between cyclotron motion and collective oscillations in two-dimensional electron systems -- offer dir…
Interaction-limited conductivity of twisted bilayer graphene revealed by giant terahertz photoresistance
A. L. Shilov, M. Kravtsov, J. Covey +15
Identifying the microscopic processes that limit conductivity is essential for understanding correlated and quantum-critical states in quantum materials. In twisted bilayer graphen…
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…
Temperature and Electron Concentration Dependences of 1/f Noise in HgCdTe -- Evidence for a Mobility Fluctuations Mechanism
Adil Rehman, Volodymyr Petriakov, Ivan Yahniuk +9
HgCdTe is a unique material with the band-gap tunable by the temperature, pressure, and cadmium content in a wide range, from 1.6 eV to inverted band-gap of -0.3 eV. Th…
