Energy harvesting from g-C3N4 piezoelectric nanogenerators

Graphitic carbon nitride (g-C3N4) is first explored in the application of energy capture by taking advantage of strong piezoelectricity derived from intrinsically non-centrosymmetric holes, leading to in-plane piezoelectricity even in multilayers or bulk structures. In the present work, we demonstrate the successful fabrication and efficient energy harvesting of g-C3N4-based piezoelectric nanogenerators (PENGs), where a several-fold enhancement...
