Our new publication “Microwave-induced capacitance resonances and anomalous magnetoresistance in double quantum wells” has been published today in Journal of Applied Physics.


Magnetotransport measurements on electron bilayer systems under low frequency continuous microwave irradiation reveal an anomalous magnetoresistance behavior. At low total imbalanced carrier densities, pronounced features in the longitudinal and Hall resistance emerge that show a surprisingly strong sensitivity to frequency, microwave power, and density. We suggest its origin to be related to resonantly induced capacitance oscillations of the two-layer system.
