The on-site Coulomb interaction U and the inter-site interaction V are varied on the x and y axis, respectively. The temperature is held constant at T=0.01. W is the half-bandwidth and the energy unit. A typical trajectory relevant for the 2D-MIT is shown by the arrow. The following phases are found: charge-density-wave metallic phase (CDW-M), charge-density-wave insulating phase (CDW-I).
