Developments in the physics of 2D electron systems during the last decade revealed a new
class of nonequilibrium phenomena in the presence of a moderately strong magnetic field …

Two-dimensional electron systems subjected to a perpendicular magnetic field absorb
electromagnetic radiation via cyclotron resonance (CR). Here we report a qualitative …

In a high-mobility two-dimensional electron gas (2DEG) in a GaAs/Al 0.3 Ga 0.7 As quantum
well we observe a strong magnetoresistance. In lowering the electron density, the …

We report on a giant negative magnetoresistance in very high mobility GaAs/AlGaAs
heterostructures and quantum wells. The effect is the strongest at B≃ 1 kG, where the …

We report on a colossal negative magnetoresistance (MR) in a GaAs/AlGaAs quantum well
which, at low temperatures, is manifested by a drop of the resistivity by more than an order of …

We report the observation of a remarkably strong microwave photoresistivity effect in a high-
mobility two-dimensional electron system subject to a weak magnetic field and low …

Low-temperature electron magnetotransport in single GaAs quantum wells with two
populated subbands is studied at large filling factors. Magneto-intersubband (MIS) and …

Nonlinear resistance of highly mobile two-dimensional electrons placed in crossed electric
and strong magnetic fields attracts considerable contemporary interest. The resistance …

We report on experimental and theoretical studies of microwave-induced resistance
oscillations in a two-dimensional electron gas over a wide range of microwave intensities …

A theory of the quantum oscillations of resistivity due to interaction of two-dimensional
electrons with impurities and acoustic phonons in the presence of perpendicular magnetic …
