In this work we report the electrical polarization can be induced by composition-graded LaAlO3-SrTiO3 solid solution. The analysis indicates that the induced polarization is attributed to the flexoelectric effect in the compositional gradient system. By a suitable combination of compositional gradient in geometry, a local conduction can be created and manipulated, delivering a new approach to obtain unveiled properties. delivering a new pathway to acquire material genome based on material inhomogeneity.
