摘要：

We study numerically the relaxation and the pinning gap of a 2D electron crystal in the presence of randomly distributed distant dopants. Our results agree with experiments and with analytic calculations based on a perturbation in the deviations of the particle positions deltar/a from the lattice positions. For parameters corresponding to the recent experimental studies (d/a congruent-to 3), the relaxation is dominated by the longitudinal mode.
