![]() Different tessellations will provide new symmetric systems to explore. Computationally, the popular tessellations used are the Archimedean tiling, but many others expect to be discovered and well-studied. molecules and can be a mix of several polygons to increase the number of possibilities. ![]() The tessellations available are constrained to the four-fold type of the phthalocyanine. In particular, the phthalocyanine molecules can be placed at each vertex or sharing edges to form tessellations. The phthalocyanine molecule is used as a brick for the construction of new bidimensional materials. In this review, we explore the bidimensional materials based on phthalocyanine molecules. Systems Ag and Au are in the physisorption range, the network preserves the natural two dimensionality of the graphene sheet and conductivity is still in the ballistic regimen. Systems Pt and Pd are in the chemisorption range and the network distortion is such that conductivity diminishes so that it is no longer in the ballistic regimen. ![]() For conductivity calculations, size and scattering potential are obtained from our calculations. Adsorption sites are the scattering centres of our systems. three different approaches frozen ripples, charged impurities and resonant scattering. Ground state properties and electronic structure calculations at DFT level are undertaken for each system. In this paper the adsorption of silver, gold, platinum and palladium cluster with n atoms (n = 1, 2, 3 and 4) and their effect on conductivity are studied. When metallic clusters are adsorbed by pristine graphene, the conductivity of the system is modified. ![]()
