Abstract

Electrodeposition can be used as a cost-effective, room temperature technique for the fabrication of thermoelectric materials, as opposed to more traditional methods, such as chemical vapour deposition or molecular beam epitaxy, that require high temperatures and vacuum conditions. This chapter deals with understanding how electrodeposition can be applied as a technique, reviewing recent developments in its use in the deposition of thermoelectric materials, and exploring the use of additives and dopants during the deposition process in order to enhance the thermoelectric properties of the material. Results are presented to show how a surfactant, sodium lignosulfonate, can be added to an electrolyte in order to produce levelled and compact Bi2Te3 thin films with a preferred crystallographic orientation, thought to offer improved thermoelectric efficiency. Doping of ternary bismuth tellurium selenide semiconductor n-type thermoelectric deposits with small fractions of copper can be used to achieve a reduced crystallite size and dramatic enhancements in thermoelectric performance.
