Melting of a two-dimensional electron lattice is studied using the molecular-dynamics technique. It is found that the system undergoes a first-order phase transition between Γ[=e²(πn)1/2κBT]=118-130. The system exhibits hysteresis in the temperature dependence of total energy and the coefficient of self-diffusion. The change in entropy on melting is found to be 0.3κB per particle.
