A thermoelectric material

Abstract

Abstract A thermoelectric material consists of an oxide with a perovskite structure, wherein the oxide is composed of a rare earth element and a transition metal element. Another thermoelectric material is in the form of a solid solution consisting of an oxide with a perovskite structure that is composed of a rare earth element and a transition metal element, wherein at least one part of the rare earth element is replaced by an alkaline-earth metal element, or at least one part of the transition metal element is replaced by another kind of transition metal element. These thermoelectric materials are particularly useful for Peltier cooling elements that produce low temperatures below room temperature.
