    摘要: Transition metals (T) of Group VIII (Co, Rh and Ir) have been prepared as semiconductor alloys with Sb, P, and As, having the general formula TX, wherein X is Sb.sub.3, P.sub.3, or As.sub.3. The skutterudite-type crystal lattice structure of these semiconductor alloys and their enhanced semiconductor properties results in semiconductor materials which may be used in the fabrication of power semiconductor devices to substantially improve the efficiency of the resulting semiconductor device. Semiconductor alloys having the desired skutterudite-type crystal lattice structure may be prepared in accordance with the present invention by using vertical gradient freeze techniques, liquid-solid phase sintering techniques, low temperature powder sintering and/or hot-pressing.

    摘要: A device for generating power to run an electronic component. The device includes a heat-conducting substrate (composed, e.g., of diamond or another high thermal conductivity material) disposed in thermal contact with a high temperature region. During operation, heat flows from the high temperature region into the heat-conducting substrate, from which the heat flows into the electrical power generator. A thermoelectric material (e.g., a Bi2Te3-based film or other thermoelectric material) is placed in thermal contact with the heat-conducting substrate. A low temperature region is located on the side of the thermoelectric material opposite that of the high temperature region. The thermal gradient generates electrical power and drives an electrical component.

    摘要: A thermally stable diffusion barrier for bonding skutterudite-based materials with metal contacts is disclosed. The diffusion barrier may be employed to inhibit solid-state diffusion between the metal contacts, e.g. titanium (Ti), nickel (Ni), copper (Cu), palladium (Pd) or other suitable metal electrical contacts, and a skutterudite thermoelectric material including a diffusible element, such as antimony (Sb), phosphorous (P) or arsenic (As), e.g. n-type CoSb3 or p-type CeFe4−xCoxSb12 where the diffusible element is Sb, to slow degradation of the mechanical and electrical characteristics of the device. The diffusion barrier may be employed to bond metal contacts to thermoelectric materials for various power generation applications operating at high temperatures (e.g. 673 K or above). Some exemplary diffusion barrier materials have been identified such as zirconium (Zr), hafnium (Hf), and yttrium (Y).

    摘要: A method of applying a physical barrier to suppress thermal decomposition near a surface of a thermoelectric material including applying a continuous metal foil to a predetermined portion of the surface of the thermoelectric material, physically binding the continuous metal foil to the surface of the thermoelectric material using a binding member, and heating in a predetermined atmosphere the applied and physically bound continuous metal foil and the thermoelectric material to a sufficient temperature in order to promote bonding between the continuous metal foil and the surface of the thermoelectric material. The continuous metal foil forms a physical barrier to enclose a predetermined portion of the surface. Thermal decomposition is suppressed at the surface of the thermoelectric material enclosed by the physical barrier when the thermoelectric element is in operation.

High Seebeck coefficients and low thermal conductivities are achieved in combination with large electrical conductivities in these filled skutterudites for large ZT values. Substituting and filling methods are disclosed to synthesize skutterudite compositions with desired thermoelectric properties. A melting and/or sintering process in combination with powder metallurgy techniques is used to fabricate these new materials.
