Electrostatic potential in a piezoelectric nanowire bent by a lateral load

The fundamental theory of nanogenerator and nanopiezotronics is based on a voltage drop created across the cross section of the NW when it is laterally deflected, with the tensile side surface in positive voltage and compressive side in negative voltage. The typical nano-system setup of a vertical p...
