  • Title: Radiation-assisted magnetotransport in two-dimensional electron gas systems: appearance of zero resistance states.
    Author: Yar A, Sabeeh K.
    Journal: J Phys Condens Matter; 2015 Nov 04; 27(43):435007. PubMed ID: 26444638.
    Abstract:
    Zero-resistance states (ZRS) are normally associated with superconducting and quantum Hall phases. Experimental detection of ZRS in two-dimensional electron gas (2DEG) systems irridiated by microwave(MW) radiation in a magnetic field has been quite a surprise. We develop a semiclassical transport formalism to explain the phenomena. We find a sequence of Zero-Resistance States (ZRS) inherited from the suppression of Shubnikov-de Haas (SdH) oscillations under the influence of high-frequency and large amplitude microwave radiation. Furthermore, the ZRS are well pronounced and persist up to broad intervals of magnetic field as observed in experiments on microwave illuminated 2DEG systems.
