Formation of stationary localized states in one-dimensional chain due to a linear impurity and a modified nonlinear impurity is studied. Furthermore, a one-dimensional chain with linear and modified nonlinear site energies at the alternate sites is studied and rich phase diagrams of SL states are obtained for all the systems we considered. The results are compared with those of the linear and nonlinear systems.
