Abstract For years to come, the increasing energy demands are anticipated all around the world. The search for devices which can meet human needs for energy in sustainable ways is indispensable and challenging. Nanotechnology shows a promising solution for this. In this project, hydrothermally synthesized ZnO nanorod thin films on fluorine-doped tin oxide substrates were characterized and examined per the thermoelectric figure of merit. The nanostructures were characterized with a scanning electron microscope and X-Ray microscopy. With the measurement of the film's Seebeck Coefficient, the ratio of the generated voltage to the applied temperature difference, the thin film was confirmed to be a promising solution waste heat recovery problems. The device shows potential for low-dimensional thermoelectric applications.
