Abstract

Piezoelectric energy harvester is one of the promising power sources for the future. The use of a ZnO nanorod as an electron transport layer seems promising due to its wide bandgap conduction band, which permits the generation of reduced resistivity due to its greater surface area. In this study, ZnO nanorods are grown hydrothermally at an annealing temperature of 90 °C. The structural characteristics are determined by scanning electron microscopy (SEM) In the meantime, the electrical characteristic is measured using I-V characteristics measurement. SEM images depict the material's surface characteristics. In addition, the I-V characteristic demonstrates that the resistivity varies with the time of ZnO nanorod layer growth. As the result the best growth time is within 7 to 9 hours.
