C1: Waste heat recovery
Thermoelectric generator devices were prepared from 36 alternating layers of SiO2/SiO2+Cu superlattice films using Magnetron DC/RF Sputtering. AFM has been used to analyze the surface of the thin films. The SiO2/SiO2+Cu samples were annealed at temperatures ranging from 500 to 700 °C in air for 1 hour, to form quantum dots and/ or clusters in the multilayer superlattice thin films to tailor the thermoelectric and optical properties of the thin film systems. The synthesized nanomaterial samples were characterized with UV-Vis-NIR Optical Absorption, Florescence, and Raman spectroscopies, Seebeck coefficients measurement systems.
Keywords: Thermoelectric properties, multi-nanolayers, figure of merit.
