Phase transitions of a lattice-model for patchy particles with tetrahedral symmetry

摘要

We present a simple lattice model which gives account of the low temperature phase equilibria of patchy particles with tetrahedral symmetry. Using such a model the phase diagram was computed as a function of the model parameters by means of Monte Carlo simulations. Depending on the details of the particle interactions a low-density ordered phase with diamond structure can appear as thermodynamically stable phase.
