Abstract We have simulated the diffusion-limited growth of dimers on a two-dimensional triangluar lattice and have found that if tips of the dirners have different polarities, the resulting clusters, due to the alignment of the dimers and polarities chosen, are Jess dense than the clusters generated without polarities. These results make our model an effective way to demonstrate the role of the sticking probabilities in the diffusion-limited aggregation.
