Radiation-induced zero-resistance states with resolved Landau levels

Abstract

The microwave-photoexcited high mobility GaAs/AlGaAs two-dimensional electron system exhibits an oscillatory-magnetoresistance with vanishing resistance in the vicinity of magnetic fields $B=[4/(4j+1)]B_f$, where $B_f=2\pi \text{f}{m}^{\ast }/e$, m${}^{\ast }$ is an the effective mass, e is the charge, \textit{f} is the microwave frequency, and $j$ =1,2,3... Here, we report transport with well-resolved Landau levels, and some transmission characteristics.
