Owing to their applications in devices such as electromechanical sensors, actuators and nanogenerators, the consideration of size-dependent properties response composites is great importance. In this study, a closed-form solution based on linear piezoelectricity, Kirchhoff’s plate theory Navier’s was developed, envisage behaviors hybrid graphene-reinforced piezoelectric composite (GRPC) plates,...

The piezo-photovoltaic effect has been recently proposed as an analogy of the flexo-photovoltaic in noncentrosymmetric ferroelectrics that are also piezoelectric nature. It demonstrated to boost photovoltaic performance under applied uniaxial mechanical loads. impact on ferroelectric domains, however, not yet studied. In this context, a nanoscale insight into well optomechanical control domains...

We present a formulation for calculating the transversal flexoelectric coefficient of nanostructures at finite deformations from first principles. Specifically, we introduce concept radial polarization to make well-defined quantity uniform bending deformations. use framework calculate group IV atomic monolayers using density functional theory. find that graphene's is significantly larger than p...
