However, ZnO-based\u00a0piezoelectric\u00a0nanogenerators (PENGs) generally rely on the exploitation of single-crystalline\u00a0nanowires\u00a0because of their self-orientation in the c-axis direction and ability to accommodate long\u00a0deformations\u00a0resulting in high piezoelectric performance. Herein, we show an innovative approach to produce PENGs by combining\u00a0polycrystalline\u00a0ZnO\u00a0layers fabricated at room temperature by plasma-assisted deposition with supported\u00a0small-molecule\u00a0organic nanowires (ONWs) acting as 1D\u00a0scaffolds. Such hybrid\u00a0nanostructures\u00a0present convoluted\u00a0core-shell\u00a0morphology, formed by a single-crystalline organic nanowire conformally surrounded by a poly-crystalline ZnO shell and combine the organic core mechanical properties with the ZnO layer piezoelectric response. In a step\u00a0forward\u00a0towards the integration of multiple functions within a\u00a0single wire, we have also developed ONW-Au-ZnO nanoarchitectures including a gold shell acting as inner electrode achieving output piezo-voltages up to 170\u202fmV. The synergistic combination of functionalities in the ONW-Au-ZnO devices promotes an enhanced performance generating piezo-currents one order of magnitude larger than the ONW-ZnO nanowires and superior to the thin film nanogenerators for equivalent and higher thicknesses.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The\u00a0thin film\u00a0configuration presents obvious practical advantages over the 1D implementation in\u00a0energy harvesting\u00a0systems such as easily manufacturing and processing, and long-lasting and stable devices.
