Effect of structural and morphological deformation on the enhancement of thermoelectric properties of zinc oxide due to the dual substitution of indium and nickel was investigated. The doped materials resemble the hexagonal wurtzite structure of the host material, with increased crystallite size and strain, indicating the inclusion of the cations with larger radius. Reduction in the optical band gap energy from 3.1 eV to 2.20 eV is observed with a red shift in the absorption edge. The donor cations doped samples have high charge carrier density, resulting an increase in the transport properties. Highest electrical conductivity and seebeck coefficient were obtained for the doped samples leading to a hike in the power factor of 1427 μW/mK 2 . The thermal conductivity decreased with doping concentration, and highest figure of merit of 0.11 was obtained.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
