Abstract

We present data on the low-frequency noise of the high-field conducting state in the insulating phase around the 1/5 fractional quantum Hall liquid at B=11.9 T and how it correlates with the strongly nonlinear I-V characteristic. The noise is characteristic of a weakly pinned two-dimensional Wigner crystal reentrant around the 1/5 liquid. For v<1/5, it reaches a peak and then vanishes in the more insulating regime (B12.7 T in our sample) where the system is better described as a 2D Wigner glass.
