Thermoelectric Characteristics of the Electrodeposited (Bi,Sb)2Te3 Films with Variation of the Electrodeposition Current Density

Article Preview

Abstract:

Electrodeposition behavior and thermoelectric properties of the p-type (Bi,Sb)2Te3 films were investigated for thermoelectric energy conversion and nanowire applications. Composition and thermoelectric properties of the electrodeposited (Bi,Sb)2Te3 films were strongly dependent on the electrodeposition current density. The (Bi,Sb)2Te3 films electrodeposited in a 30mM solution of the 5mM Bi-15mM Sb-10mM Te concentration at current densities of 0.3~0.5 mA/cm2 exhibited the power factors of 2~3.4 ×10-4 W/K2-m, which were equivalent to the values reported for the sputter-deposited (Bi,Sb)2Te3 films.
