Microwave-induced zero-resistance states on 2D electron gas: theoretical explanation and temperature dependence
نویسندگان
چکیده
A new theoretical model is presented in which the radiation-induced zero-resistance states and resistivity oscillations are analyzed. The basis of our model is an exact solution for the harmonic oscillator wave function in the presence of radiation and a perturbation treatment for elastic scattering due to randomly distributed charged impurities. Following this model most experimental results are reproduced: zeroresistance states, resistivity oscillations and the dependence of resistivity with temperature, where a physical model of interaction with acoustic phonon is presented, and an activation energy is calculated. q 2005 Elsevier Ltd.

Microwave-induced resistance oscillations and zero resistance states in 2D bilayer systems
: We report on theoretical studies of recently obtained experimental results on microwave-induced resistance oscillations and zero resistance states in Hall bars with two occupied subbands. In these experiments, resistance presents a peculiar shape which appears to have a built-in interference effect not observed before. We apply the microwave-driven electron orbit model, which implies a radiat...
متن کاملKubo formula for Floquet states and photoconductivity oscillations in a 2 D electron gas
The recent discovery of the microwave induced vanishing resistance states in a two dimensional electron system (2DES) is an unexpected and surprising phenomena. In these experiments the magnetoresistance of a high mobility 2DES under the influence of microwave radiation of frequency ω at moderate values of the magnetic field, exhibits strong oscillations with zero-resistance regions governed by...
متن کاملFrom zero resistance states to absolute negative conductivity in microwave irradiated two-dimensional electron systems
Recent experimental results regarding a two-dimensional electron gas subjected to microwave radiation reveal that magnetoresistivity, apart from presenting oscillations and zero resistance states, can evolve to negative values at minima. Here the authors present a theoretical model which explains the transition from zero resistance states to absolute negative conductivity in terms of multiphoto...
متن کاملTemperature and magnetic field dependence of radiation-induced magneto-resistance oscillations in a two-dimensional electron gas
In the last two decades, specially since the discovery of the Quantum Hall Effect, a lot of work and progress has been made in the study of two-dimensional electron gas (2DEG) and very important and unusual properties have been discovered when those systems are subjected to the influence of external AC and DC fields. Recently, two experimental groups[1, 2] have announced the existence of vanish...
متن کاملMicrowave zero-resistance states in a bilayer electron system.
Magnetotransport measurements on a high-mobility electron bilayer system formed in a wide GaAs quantum well reveal vanishing dissipative resistance under continuous microwave irradiation. Profound zero-resistance states (ZRS) appear even in the presence of additional intersubband scattering of electrons. We study the dependence of photoresistance on frequency, microwave power, and temperature. ...
