Simulation Studies of Random Sequential Adsorption (RSA) of Mixture of Two-Component Circular Discs

Competitive random sequential adsorption of binary mixtures of disks and discorectangles

“…At each deposition attempt, the disk or discorectangle was selected randomly with the probability p d or p ε = 1 − p d , and the overlapping with previously deposited particles was forbidden. Applied competitive RSA model is rather similar to the previously reported for binary mixtures of disks [26]. For detecting overlapping the optimized RSA algorithm based on tracking of local regions was used [8,9].…”

“…In the multistep models the substrates are covered by the particles of different sort sequentially. The deposition of mixtures of disks have been intensively discussed for the competitive [23][24][25][26] and the multi-step [27][28][29][30][31][32] RSA models. Particularly the multi-step depositions on heterogeneous, partially pre-covered, pre-patterned of fractal surfaces (multistep RSA models) were studied.…”

Two-stage random sequential adsorption of discorectangles and disks on a two-dimensional surface

“…The spatially continuous RSA models related to simultaneous deposition of mixtures of particles on 2D planar surface have been investigated [17,[23][24][25]. In early studies the adsorption of mixture of hard disks of greatly differing particle diameters was studied theoretically [17].…”

“…The different time dependencies of coverage φ(t) were observed for the large and small disks. Simulation studies of RSA of binary mixture of disks at different relative rate constants have been recently performed [24]. The radial distribution function and volume distribution of pores were analyzed.…”

Jamming and percolation in the random sequential adsorption of a binary mixture on the square lattice

“…Despite its simplicity, the model provides deep insight into experimentally observed phenomena, related to chemisorption on surfaces [12][13][14], adsorption on membranes [15], adsorption of colloids [16][17][18][19] and of proteins [20], Rydberg excitation [21], and ion implantation in semiconductors [22]. One of the variants of the model which still leads to surprising results is the one focusing on the competitive adsorption of two species (binary mixture) differing in shape and/or sizes [22][23][24][25][26][27][28][29][30][31][32][33][34][35], which also includes adsorption in the presence of quenched defects [36][37][38][39][40][41][42][43]. For example, it has been shown recently by numerical simulations that the RSA model does not exhibit its universal critical features at the so-called jamming and percolation points when such defects yield strong long-range spatial correlations [44].…”
