Abstract: Reduced dimensionality in two dimensions is a topic of current interest. We use model systems to investigate the statistical mechanics of ideal networks. The tilings have possible applications such as the 2D locations of pore sites in nanoporous arrays (quantum dots), in the 2D hexagonal structure of graphene, and as adsorbates on quasicrystalline crystal surfaces. We calculate the statistical mechanics of these networks, such as the partition function, free energy, entropy, and enthalpy. The plots of these functions versus the number of links in the finite networks resultin power law regression. We also determine the degree distribution, which is acombination
of power law and rational function behavior. In the large-­ scale limit, the degree of these 2D networks approaches3, 4,and 6, in agreement with the degree of the regulartilings.
In comparison, a Penrose tiling has a degree also equal to about 4.
