Resumen:
One of the most studied subjects in Mechanical Statistical is the percolation phase transitionoccurring in Randon Sequential Adsorption (RSA) models of extended objects on two-dimensional lattices.In this type of models, the objects are randomly and irreversibly deposited forming a single monolayer. The final state generated by RSA is a disordered state (known as jamming state), in which no more objects can be deposited due to the absence of free space of appropriate size and shape. Thus, a competition between percolation and jammingis established. The study of these systems in the regime of monolayer offers a basic representation of more complex processes such as adsorption of proteins on solid surfaces, of particles on a biological membrane, of latex spheres on a silica surface, chemisorption of large molecules, etc. In spite of the number of contributions to this problem, there are many aspects which are not yet completely solved. In fact, most of the studies are devoted to deposition at monolayer; however, less attention has received the development of more realistic models considering the formation of a multilayer. The objective of this work is to provide a thoroughstudy in this direction. For this purpose, extensive numerical simulations supplemented by analysis usingfinite-size scaling theory have been carried out to study the percolation and jamming behaviour in a RSA modelof linear rigid k-mers on bilayer square lattices (growth 2D+1D). Percolation and jamming thresholds are reported as a function of the k-mer size and the number of deposited layers. In addition, the complete set of critical exponents characterizing the jamming and percolation phase transitions is determined.
