The self-assembly of ink molecules in dip-pen nanolithography (DPN) was theoretically studied for the first time. The dynamics of the self-assembly was modeled as a two dimensional random walk on a square lattice. Varying the magnitudes of deposition rate and tip scan speed relative to the diffusion time scale of ink molecules, the patterns generated by DPN were determined.
