Effects of Group-I Elements on Output Voltage Generation of ZnO Nanowires Based Nanogenerator; Degradation of Screening Effects by Oxidation of Nanowires
Here, we report the successful incorporation of group I elements (K, Na, Li) to ZnO nanowires.Three distinct (2, 4, and 6 wt.%) doping concentrations of group I elements have been used to generate high piezoelectric voltage by employing a vertically integrated nanowire generator Stand (VING) structure.X-ray photoelectron spectra (XPS) indicated the
