Abstract
Dimethyl sulfoxide (DMSO) electrolytes were investigated for the electrodeposition of bismuth telluride films for thermoelectric applications. The investigation revealed the influences of electrolyte ion concentration, deposition potential, and temperature on the alloy composition. Full composition range of bismuth telluride BixTey materials could be prepared by varying either electrolyte ion concentration or deposition potential. The film morphology was found smooth at the stoichiometric composition and affected by the film composition, rather than deposition conditions. The highest Seebeck coefficient observed for n-type films was -134 uV/K (unannealed) and +150 uV/K for p-type (annealed).
