A multiphase thermoelectric material includes a titania-based semiconducting phase and a half-metal conducting phase. The multiphase thermoelectric material is advantageously a nanocomposite material wherein the constituent phases are uniformly distributed and have crystallite sizes ranging from about 10 nm to 800 nm. The titania-based semiconducting phase can be a mixture of sub-stoichiometric phases of titanium oxide that has been partially reduced by the half-metal conducting phase. Methods of forming a multiphase thermoelectric material are also disclosed.
