Simulated annealing followed by cluster flipping is done to obtain the minimum possible energy state (ground state) in a two-dimensional lattice model of Coulomb Glass. As disorder is increased one gets transition from Anti-ferromagnetic to disordered state. We are getting frozen domains in the transition and disordered region. Analysis of the structural distribution of the domains shows that the domains are non compact in the transition region and are fractal in the disordered region. This along with the analysis of fluctuation energies shows that the domains behave in a way different from the Imry-Ma argument.
