  We propose a primitive model of Janus ellipsoids that represent particles
with an ellipsoidal core and two semi-surfaces coded with dissimilar
properties, for example, hydrophobicity and hydrophilicity, respectively. We
investigate the effects of the aspect ratio on the self-assembly morphology and
dynamical aggregation processes using Monte Carlo simulations. We also discuss
certain differences between our results and those of earlier results for Janus
spheres. In particular, we find that the size and structure of the aggregate
can be controlled by the aspect ratio.
