radiation on the recently discovered microwave-induced resistance
oscillations in state-of-the-art highest purity 2D electron systems. A
quasi-optical setup allows us to tune in situ between different
circular as well as linear polarization states. We find that the
microwave-induced zero resistance and the resistance oscillations are
notably immune to changes in the polarization. This observation is
discrepant with a number of proposed theories. Deviations for different
polarizations only occur for a bolometric contribution to the
resistance associated with the resonant heating at the cyclotron
resonance itself. (c) 2006 Published by Elsevier B.V. | Free Keywords: | zero resistance; microwave photoconductivity; 2D electron system | External Publication Status: | published | Document Type: | Article |
