摘要：
Using classical Monte Carlo approach we analyze two-dimensional Falicov-Kimball model away from half-filling. Both the weak and the strong interaction regimes are considered. We found that in the former case stripe configurations are the stable ones, whereas in the latter case the phase separation minimize the energy. We present also the spectral properties of the system.
