Mott insulator and charge ordered phases in a three-component Falicov-Kimball model is studied by the dynamical mean-field theory. The three-component Falicov-Kimball model consists of itinerant single-component and localized two-component fermions, and local Coulomb interactions between the components. Self consistent equations for charge susceptibilities are derived. It is found that the metal-insulator transition occurs at high temperature, whereas charge ordering is stable at low temperature. Different Mott insulator and charge ordering patterns are presented.
