    摘要: A process for manufacturing stand-alone thin films is provided. The process includes providing a substrate, depositing a carbon-containing sacrificial layer onto the substrate and the depositing a thin film onto the carbon-containing sacrificial layer. Thereafter, the substrate, carbon-containing sacrificial layer and thin film structure are exposed to oxygen at an elevated temperature. The oxygen reacts with the carbon-containing sacrificial layer to produce carbon dioxide and remove carbon from the sacrificial layer, thereby generally burning away the sacrificial layer and affording for an intact stand-alone thin film to separate from the substrate.

    摘要: A thermoelectric material comprises core-shell particles having a core formed from a core material and a shell formed from a shell material. In representative examples, the shell material is a material showing an appreciable thermoelectric effect in bulk. The core material preferably has a lower thermal conductivity than the shell material. In representative examples, the core material is an inorganic oxide such as silica or alumina, and the shell material is a chalcogenide semiconductor such as a telluride, for example bismuth telluride. A thermoelectric material including such core-shell particles may have an improved thermoelectric figure of merit compared with a bulk sample of the shell material alone. Embodiments of the invention further include thermoelectric devices using such thermoelectric materials, and preparation techniques. The use of core-shell nanoparticles allows highly uniform nanocomposites to be formed, and embodiments of the invention also includes other materials and devices using core-shell particles.
