Abstract
Material tensors are identified in ferroelectric nanostructures via the use of first-principles-based simulations and analytical developments. In particular, one of such tensors represents a form of electromechanical coupling occurring at the nanoscale, while another tensor can be considered as analogous of dielectric susceptibility when going from bulk to nanoparticles. The reasons behind the existence of such overlooked tensors are discussed.
