Electrically-conductive materials for thermoelectric and optical applications

Electrically-conductive materials are important for a variety of industrial applications. For instance, thermoelectric materials may be used to recover waste heat in automobiles, provide on-chip cooling for integrated circuit systems, and generate electricity in subsea and space applications. These materials utilize the Peltier effect to convert an applied temperature gradient to a voltage, and vice versa. On the other hand, transparent conducting materials are required for the production of advanced devices ranging from displays to electrodes for thin-film photovoltaics, since they allow light to pass through to the photoactive layers in the device to generate charge carriers, while conducting these carriers out of the device. We are designing materials with high electrical conductivity and low processing costs.
