Resumen:
In this paper, the percolation of a linear segments of size k and b k-mers of different structures
and forms deposited on a square lattice contaminated with previously adsorbed impurities have been
studied. The contaminated or diluted lattice is built by randomly selecting a fraction of the elements
of the lattice either bonds or sites which are considered forbidden for deposition. Results are
obtained by extensive use of finite size scaling theory. Thus, in order to test the universality of the
phase transition occurring in the system, the numerical values of the critical exponents were
determined. The characteristic parameters of the percolation problem are dependent not only on the
form and structure of the k-mers but also on the properties of the lattice where they are deposited.
A phase diagram separating a percolating from a nonpercolating region is determined as a function
of the parameters of the problem. A comparison between random site and random bond percolation
in the presence of impurities on the lattice is presented.a linear segments of size k and b k-mers of different structures
