Flexoelectricity is a size-dependent electromechanical coupling mechanism, existing in a wide variety of materials, including cellular membranes, liquid crystals, carbon-based materials, and piezoelectric and non-piezoelectric crystals. Flexoelectricity manifests no- ticeably at the nanoscale, therefore experimental observation of this phenomenon is more difficult compared to other electromechanical coupling mechanisms such as piezoelectric- ity. This motivates us to develop theoretical and computational models to investigate flexoelectricity in nanostructures.
