Abstract. The effect of correlated hopping of d-electrons between Nearest-Neighbor (NN) sites on Mixed-Valent systems has been studied with the theoretical support of extended Falicov-Kimball model (EFKM). Both the thermodynamic and ground state properties have been investigated through the exact diagonalization method. The f-electron density <n_i^f> decreases with the f-level energy (E) showing valence transition. The maximum coulomb correlation is seen for lower correlated hopping interaction (K). The specific heat curves show sharp single-peak structure. However, for higher values of f-level energy E, an inclination to double-peak structure is observed at higher temperatures (T). The system becomes more disordered with the increase of hopping value.
