Abstract

The liquid-solid transition of two-dimensional electrons with long-range Coulomb interaction was studied. It was shown how the Mott insulator at n=1, charge orders at 0<n<1, and the Wigner lattice at n→1 are connected. The PIRG result with quantum fluctuations taken in a correct way showed a rapid increase of rs for the transition when the commensurability becomes weak.
