Microwave-induced Hall resistance in bilayer electron systems

Abstract

The influence of microwave irradiation on dissipative and Hall resistance in high-quality bilayer electron systems is investigated experimentally. We observe a deviation from odd symmetry under magnetic field reversal in the microwave-induced Hall resistance $\Delta R_{xy}$ whereas the dissipative resistance $\Delta R_{xx}$ obeys even symmetry. Studies of $\Delta R_{xy}$ as a function of the microwave electric field and polarization exhibit a strong and non-trivial power and polarization dependence. The obtained results are discussed in connection to existing theoretical models of microwave-induced photoconductivity.
