ABSTRACT:
A thermoelectric material which exhibits a high thermoelectric performance even at high temperatures is shown and described. A thermoelectric material is provided with a plurality of conductive layers made of a first semiconductor only and a plurality of barrier layers made of a second semiconductor only, which are alternatingly arranged, a diffusion-preventive layer being interposed between neighboring conductive layers and barrier layers. Diffusion between the conductive layers and the barrier layers under high-temperature conditions is prevented, and the thermoelectric material maintains high performance standards at high temperatures.
