Radiowave-induced Resistance Oscillations
Abstract
Microwave-induced resistance oscillations (MIROs) occur when a 2D electron gas is subjected to radiation of frequency ω= 2 πf and varying magnetic field B. MIROs are periodic in 1/B, with the period determined by the radiation frequency ω, and their amplitude scales with the radiation power. Stepping from single-photon transitions between Landau levels, MIROs are found on the low-field side of the cyclotron resonance, ωc ≲ ω, where ωc is the cyclotron frequency. Here, we report on another class of magneto resistance oscillations, which are induced by high-intensity radiation in the radio frequency range and occur at ωc ≫ ω. These oscillations are independent of frequency ω, can be either 1/B or 1/B2-periodic, and their period is controlled by the radiation electric field. We further show that using a displacement model in the limit of short-range (``sharp'') disorder we can extract the radiation field and the width of the cyclotron resonance.

AB - Microwave-induced resistance oscillations (MIROs) occur when a 2D electron gas is subjected to radiation of frequency ω= 2 πf and varying magnetic field B. MIROs are periodic in 1/B, with the period determined by the radiation frequency ω, and their amplitude scales with the radiation power. Stepping from single-photon transitions between Landau levels, MIROs are found on the low-field side of the cyclotron resonance, ω_c ≲ ω, where ω_c is the cyclotron frequency. Here, we report on another class of magneto resistance oscillations, which are induced by high-intensity radiation in the radio frequency range and occur at ω_c ≫ ω. These oscillations are independent of frequency ω, can be either 1/B or 1/B^2-periodic, and their period is controlled by the radiation electric field. We further show that using a displacement model in the limit of short-range (``sharp'') disorder we can extract the radiation field and the width of the cyclotron resonance.
