Effect of the number of patches on the growth of networks of patchy   colloids on substrates
  We investigate numerically the irreversible aggregation of patchy spherical colloids on a flat substrate. We consider $n$-patch particles and characterize the dependence of the irreversible aggregation kinetics on $n$. For all values of $n$, considered in this study, the growing interface of the aggregate is in the Kardar-Parisi-Zhang universality class, although the bulk structure exhibits a rich dependence on $n$. In particular, the bulk density varies with $n$ and the network is more ordered for particles with fewer patches. Preferred orientations of the bonds are also observed for networks of particles with low $n$.
