Abstract

Wigner solids in two-dimensional electron systems in high magnetic field B exhibit a striking, microwave or rf resonance, that is understood as a pinning mode. The temperature, T_m, above which the resonance is absent, is interpreted as the melting temperature of the solid. Studies of T_m for many B and many sample densities n show that T_m is a function of the Landau level filling v alone for a given sample. This indicates that quantum mechanics figures importantly in the melting. T_m also appears to be increased by larger sample disorder.
