New materials semi - conductors thermoelectric is based on silver, thallium and tellurium and application to a heat pumps

摘要

The invention relates to thermoelectric semiconductor materials. The thermoelectric semiconductor materials based on silver, thallium and tellurium, according to the invention, are represented by the general formula (I) IMAGE in which x, y and z are between -0.10 and +0.10, but are not simultaneously zero. These materials have a figure of merit greater than 1, thus enabling them to be applied to Peltier-effect thermoelectric heat pumps.
