On the coupling effects of piezoelectricity and flexoelectricity in piezoelectric nanostructures [PDF]

open access: yesAIP Advances, 2017
Flexoelectricity is a novel kind of electromechanical coupling phenomenon that is prevalent in all solid dielectrics and usually of vital importance in nanostructures and soft materials. Although the fundamental theory of flexoelectric solids and related beam or plate theories were extensively studied in recent years, the coupling effect of ...
