Phys. Rev. Lett. 103, 266808 (2009) [4 pages]Novel Radiation-Induced Magnetoresistance Oscillations in a Nondegenerate Two-Dimensional Electron System on Liquid HeliumReceived 2 November 2009; published 31 December 2009 We report the observation of novel magnetoresistance oscillations induced by the resonant intersubband absorption in nondegenerate 2D electrons bound to the surface of liquid 3He. The oscillations are periodic in B-1 and originate from the scattering-mediated transitions of the excited electrons into the Landau levels of the first subband. The structure of the oscillations is affected by the collision broadening of the Landau levels and by many-electron effects. © 2009 The American Physical Society URL:
