On the phase of oscillatory microwave photoresistance and zero-resistance states

Abstract

We present phenomenological analysis of the period and the phase of oscillatory microwave photoresistance (OMP) and zero-resistance states (ZRS) recently observed in 2D electron systems. The results demonstrate that as OMP evolves into ZRS with increasing magnetic field, the absolute value of the phase becomes progressively smaller, decreasing roughly as 1/B. Virtually eliminating a phase-shift and resulting in different periodicities for the maxima and minima, such specific dependence is supported by a simple model based on oscillatory density of states. Finally, it follows that fine structures first reported in Ref. 3 can be viewed as an experimental evidence for multi-photon processes.
