We demonstrate that the morphotropic phase boundary of the lead-free ferroelectric system (NBT-xBT) can be uniquely distinguished by a reduced polarizationstate along with a non-uniform attening of the local potential function of A- and B-site cationsof the perovskite-type structure. This establishes a robust structure-property connections based onthe atomic-level structural correlations which elucidates the long-standing question: why the MPBof NBT-xBT does not excel as much as Pb-based materials do; and further help to develop strategyin designing ecient lead-free ferroelectric systems.
