Outline of Final Research Achievements

In this study, external fields including temperature field and magnetic field were employed during voltage stressing experiments to clarify their effects on ionic migration. On this basis, the fabrication of metal micro/nanomaterials was efficiently improved with controlled ionic migration. Moreover, a protype of piezoelectric polymer-based nanocomposites were demonstrated, which provides the guidelines for the potential performance enhancement of piezoelectric nanocomposites.
