                         strain, adhesion strength, and lattice symmetry on the complex 
                         Moire patterns that form in ultrathin films of honeycomb symmetry 
                         adsorbed on compact triangular or honeycomb substrates. The method 
                         used is based on a complex Ginzburg-Landau model of the film that 
                         incorporates elastic strain energy and dislocations. The results 
                         indicate that different symmetries of the heteroepitaxial systems 
                         lead to distinct types of domain wall networks and phase 
                         transitions among various surface Moire patterns and 
                         superstructures. More specifically, the results show a dramatic 
                         difference between the phase diagrams that emerge when a honeycomb 
                         film is adsorbed on substrates of honeycomb versus triangular 
                         symmetry. It is also shown that in the small deformation limit, 
                         the complex Ginzburg-Landau model reduces to a two-dimensional 
                         sine-Gordon free energy form. This free energy can be solved 
                         exactly for one dimensional patterns and reveals the role of 
                         domains walls and their crossings in determining the nature of the 
                         phase diagrams.",
