Abstract

Nanostructured thermoelectric semiconductors are a promising material to convert waste heat to electricity for energy regeneration due to improvement of Seebeck coefficient and thermal conductivity reducing. Among various thermoelectric materials, bismuth telluride based alloys are the most used in the fabrication of TE devices. The processes associated with the electrodeposition of (Bi,Sb)2Te3 nanowires and films are reported along with an analysis of the composition, morphology and structure of resulting materials. Electrochemical behavior was examined using cyclic and linear voltammetry and electrochemical impedance spectroscopy techniques..
