Role of an in-plane field in 2D magnetotransport assisted by microwaves

We present a theoretical approach to study the effect of an in-plane magnetic field on the microwave-assisted transport properties of a two-dimensional electron system. Experimental evidences show that microwaves induce a clear quenching of resistance oscillations and zero resistance states. In our theoretical proposal we explain this result in terms of the microwave-driven harmonic motion performed by the electronic orbits and how this motion is increasingly damped by the in-plane field.
