The electronic structures of pure and Nb 5+ , La 3+ doped ferroelectric PbTiO 3 have been calculated with discrete variation Xα(DV - Xα) embedded cluster method. Based on the relative distribution of partial density of states (PDOS) of Ti 4+ , Nb 5+ , La 3+ , and Pb 2+ ions. We could clarify the resistant effect of Nb 5+ , La 3+ doping on the ferroelectric fatigue in PbTiO 3 based material system (PZT).
