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

The different variants of two-stage random sequential adsorption (RSA) models for packing disks and discorectangles on a two-dimensional (2D) surface were investigated. In the SD (sticks+disks) model, first deposited then added. DS (disks+sticks) At stage particles up to selected concentration at final (second) saturated (jamming) state. main parameters stage, aspect ratio $\ensuremath{\varepsilon}$ (length diameter $\ensuremath{\varepsilon}=l/d$) disk $D$. All distances measured using value $d$ as unit measurement linear dimensions, was varied in interval $D\ensuremath{\in}[1\ensuremath{-}10]$, $\ensuremath{\varepsilon}\ensuremath{\in}[1\ensuremath{-}50]$. dependencies jamming coverage second versus analyzed. presence both regulated maximum possible ${D}_{\mathrm{max}}$ (SD model) or ${\ensuremath{\varepsilon}}_{\mathrm{max}}$ (DS model). This behavior explained by deposition into triangular elongated pores formed stage. percolation connectivity with hard core soft shell structure disconnectedness ensured overlapping shells. also
