Abstract

We report on systematic studies of I-V and noise in the insulating phase around the 1 5 FQH liquid at B = 11.9 T. The noise and I-V data are correlated, and together they are consistent with a weakly pinned Wigner crystal for B below and immediately above the 1 5 FQH liquid. For B ≥ 12.7 T, the system is in a more insulating regime, in which the noise vanishes, and which could be described as a Wigner glass. Preliminary results of a search for resonances or Shapiro steps in a 2DES are also presented.
