Role of phase separation in nanocomposite indium-tin-oxide films for transparent thermoelectric applications

We report that oxygen vacancies have a profound impact on phase separation and thermoelectric properties of ITO films grown at room temperature. Oxygen vacancies in non-stoichiometric In1.8Sn0.2O2.5 films aided the formation of In-rich metallic clusters. It yields a high electrical conductivity σ = ...
