Electromechanical characteristics of ZnO:Al nanorods.
In this study, we explore the effect of aluminum doping on the mechanical, piezoelectric, and semiconductive properties of zinc oxide (ZnO) nanorods using scanning probe microscopy. The results show that the size of ZnO:Al nanorods can be changed by tuning the dopant concentrations during nanorod growth. The average surface potentials of the samples were -42.2-34.4 mV. Single nanorod bending generation output surface potentials were 0.05-0.08 V. The power density per unit substrate area was 0.72 nW/mm(-2) for a device outputting ultrasonic wavelengths.
