Percolation connectivity in deposits obtained usingcompetitive random sequential adsorption of binarydisk mixtures

Condensed Matter Physics
Connectedness percolation phenomena in the two-dimensional (2D) packing of binary mixtures of disks with different diameters were studied numerically. The packings were produced using random sequential adsorption (RSA) model with simultaneous deposition
