Electricity generation based on vertically aligned PbZr0.2Ti0.8O3 nanowire arrays
چکیده انگلیسی

We statistically demonstrated the electricity generation from individual vertically-aligned/epitaxial PbZr0.2Ti0.8O3 (PZT) nanowires (NWs) using a conductive atomic force microscope (AFM). The measured outputs were analyzed in reference to the theoretically calculated piezopotential distribution in a bent NW. Our results show that the performance of the PZT NWs for electricity generation is at the same level as that of ZnO NWs although the piezocoefficient of PZT is high, due to high relative dielectric constant of PZT. Systematic investigating piezoelectricity from single PZT NWs will be useful for optimizing the performance for PZT nanogenerator applications.

► The electricity generation from individual vertically-aligned, epitaxial PZT NWs.
► The piezopotential distribution was calculated using the Lippman theory.
► The electricity generation from the PZT NWs is comparable to that from ZnO NWs.
