Pinning modes and interlayer correlation in high magnetic field bilayer Wigner solids

Abstract

We report studies of pinning mode resonances in the low total Landau filling (ν) Wigner solid of a series of bilayer hole samples with negligible interlayer tunneling, and with varying interlayer separation d. Comparison of states with equal layer densities (p,p) to single layer states (p,0) produced {in situ} by biasing, indicates that there is interlayer quantum correlation in the solid at small d. Also, the resonance frequency at small d is decreased just near ν=1/2 and 2/3, indicating the importance in the solid of correlations related to those in the fractional quantum Hall effects.
