“…[8][9][10][11][12] Thus far, all experimental observations of MIRO have been limited to direct current (dc) measurements. 1,[3][4][5][6][13][14][15] However, recent high-frequency contactless studies of MIRO using coplanar, 16 resonator, 17 and capacitive 6,18,19 techniques have produced controversial results. The controversies are speculated to originate from the fact that all the experiments were limited to very narrow frequency ranges of the probe signal.…”

In this paper, the high-frequency (f = 0.05-10 GHz) magnetoresistance of a two-dimensional electron system is studied in the regime of microwave-induced resistance oscillations (MIRO). For this purpose, we employed a technique based on measuring the attenuation of a broadband coplanar transmission line placed on the sample surface, with the sample simultaneously being subjected to external microwave irradiation of frequency F = 40-140 GHz. In the f 1 GHz probe frequency range, the coplanar waveguide transmission exhibits several features that repeat the MIRO measured on the same sample using the conventional dc transport technique. At higher probe signal frequencies f , the MIRO features in transmission are significantly suppressed. In particular, for a microwave irradiation frequency of F = 80 GHz, the first two features of the waveguide transmission decrease by an order of magnitude at f 1 = 3.0 GHz and f 2 = 1.5 GHz, respectively.

Giant microwave photoresistivity in high-mobility quantum Hall systems

et al. 2011

We report the observation of a remarkably strong microwave photoresistivity effect in a high-mobility twodimensional electron system subject to a weak magnetic field and low temperature. The effect manifests itself as a giant microwave-induced resistivity peak which, in contrast to microwave-induced resistance oscillations, appears only near the second harmonic of the cyclotron resonance and only at sufficiently high microwave frequencies. Appearing in the regime linear in microwave intensity, the peak can be more than an order of magnitude stronger than the microwave-induced resistance oscillations and cannot be explained by existing theories.

The phenomena of the microwave induced zero resistance states (MIZRS) and the microwave induced resistance oscillations (MIRO) were discovered in the ultraclean two-dimensional electron systems in 2001 -2003 and have attracted great interest of researchers. In spite of numerous theoretical efforts the true origin of these effects remains unknown so far. We show that the MIRO/ZRS phenomena are naturally explained by the influence of the ponderomotive forces which arise in the near-contact regions of the two-dimensional electron gas under the action of microwaves. The proposed analytical theory is in agreement with all experimental facts accumulated so far and provides a simple and self-evident explanation of the microwave frequency, polarization, magnetic field, mobility, power and temperature dependencies of the observed effects.
