Nonlinear effects in microwave photoconductivity of two-dimensional electron systems
Victor Ryzhii,Robert A. Suris +1 more
TL;DR: In this paper, a model for microwave photoconductivity of two-dimensional electron systems in a magnetic field which describes the effects of strong microwave and steady-state electric fields is presented.
Journal ArticleDOI
Cyclotron radiation and emission in graphene
TL;DR: Aoki et al. as discussed by the authors theoretically examined the pecularity in the cyclotron radiation and emission in graphene in terms of the optical conductivity and relaxation rates to propose that graphene in magnetic fields can be a candidate for realizing the Landau-level laser.

Cyclotron radiation and emission in graphene
TL;DR: In this article, the optical conductivity for graphene in magnetic fields with the linear response theory was calculated, where the effect of impurities was incorporated with Ando's self-consistent Born approximation.
Journal ArticleDOI
Quantum Hall effect in exfoliated graphene affected by charged impurities: Metrological measurements
TL;DR: In this paper, the quantum Hall effect (QHE) was quantized within 5 parts in the expected rational fractions of the von Klitzing constant in monolayer and bilayer exfoliated graphene.
Journal ArticleDOI
Electronic Processes at the Breakdown of the Quantum Hall Effect
TL;DR: In this article, the energy gain and loss of a two-dimensional electron system in long-range potential fluctuations are studied theoretically at the breakdown of the quantum Hall effect, at the same time as the energy loss.

Two-Dimensional Magnetotransport in the Extreme Quantum Limit
TL;DR: The formation of a Wigner solid or charge-density-wave state with triangular symmetry is suggested as a possible explanation for the formation of the Hall plateau in magnetotransport of high-mobility, two-dimensional electrons as mentioned in this paper.
Journal ArticleDOI
Quantized Hall conductance, current carrying edge states, and the existence of extended states in a two-dimensional disordered potential
TL;DR: In this article, the role of the edge states in the quantized Hall conductance is discussed in the context of the general explanation of Laughlin's analysis and the existence of extended states in a weakly disordered two-dimensional system, when a strong magnetic field is present.
Journal ArticleDOI
Absence of backscattering in the quantum Hall effect in multiprobe conductors
TL;DR: This work considers both ideal contacts without elastic scattering and also disordered contacts, and finds that the quantum Hall effect occurs only if the sample exhibits at least two sets of equilibrated edge states which do not interact via elastic or inelastic scattering.
Journal ArticleDOI
Electrostatics of edge channels.
TL;DR: A quantitative electrostatic theory of the gate-induced confinement of two-dimensional electron gas (2DEG) in the quantum Hall regime is proposed and enables results obtained in experimental studies of edge-state equilibration to be explained.
Journal ArticleDOI
Stability of the wurtzite-type structure under high pressure: GaN and InN.
TL;DR: High-pressure in situ x-ray-diffraction studies on GaN and InN have been carried out using an imaging-plate technique and a diamond-anvil cell and the trend in the transition pressures of the III-V nitrides is discussed in terms of various ionicity scales.
