A degraded mobility of 5.2× 10 5 cm 2 V− 1 s− 1 but a long quantum scattering time of 2.3 ps
at the hole density of 2.25× 10 11 cm− 2 were obtained from a two-dimensional hole gas in a …

We demonstrate that the long-debated immunity of the microwave-induced resistance
oscillations (MIRO) to the sense of circular polarization is in fact not an inherent property of …

We report on the study of terahertz radiation-induced MIRO-like oscillations of
magnetoresistivity in GaAs heterostructures. Our experiments provide an answer on two …

Considering the quantum dynamics of two-dimensional electron gas (2DEG) exposed to
both a stationary magnetic field and an intense high-frequency electromagnetic wave, we …

We investigate the effect of surface tunneling on charge distributions of two-dimensional
hole gases (2DHGs) in undoped Ge/GeSi heterostructures. As in the electron channel case …

We report on an observation of a fractional quantum Hall effect in an ultrahigh-quality two-
dimensional hole gas hosted in a strained Ge quantum well. The Hall resistance reveals …

When high-frequency radiation is incident upon graphene subjected to a perpendicular
magnetic field, graphene absorbs incident photons by allowing transitions between nearest …

Microwave induced resistance and photovoltage oscillations were investigated in Mg x Zn
1− x O/ZnO heterostructures. The physics of these oscillations is controlled significantly by …

The temperature dependence of microwave-induced resistance oscillations (MIRO),
according to the theory, originates from electron-electron scattering. This scattering affects …

The polarization dependence of the photoconductivity response at cyclotron-resonance
harmonics in a nondegenerate two-dimensional (2D) electron system formed on the surface …
