Temperature dependence of Hall-field induced resistance oscillations in 2D Electron Systems

A few years ago a new class of resistance oscillations was discovered in two-dimensional electron systems subject to weak magnetic fields and strong dc electric fields [1]. These oscillations, termed Hall field induced resistance oscillations (HIRO), are believed to originate from commensurability between the cyclotron diameter and real-space separation between Hall field tilted Landau levels. Here, we study temperature dependence of these oscillations in a very-high mobility two-dimensional electron system. Our results suggest that, in contrast to Shubnikov-de Haas effect, HIRO are sensitive to electron-electron interactions modifying the single particle lifetime. [1] C. L. Yang, J. Zhang, R. R. Du, J.
