Improved thermoelectric performance of Bi2Se3 alloyed Bi2Te3 thin films via low pressure chemical vapour deposition
Abstract
Thermoelectric generators are attractive for autonomous sensor systems where regular battery replacement would not only cause an increase in the maintenance costs and discontinuity in the operation, but also destroy the concept of a truly autonomous system. Micro-thermoelectric generators utilise thin films of material for energy harvesting which can greatly reduce the amount of material used, which is especially important for rare elements such as tellurium. Thin films of Bi<sub>2</sub>Te<sub>3</sub> were successfully prepared via a single source precursor CVD method. The thermoelectric performance of these films is improved by alloying a Bi<sub>2</sub>Se<sub>3</sub> precursor to deposit ternary Bi<sub>2</sub>Te<sub>3-x</sub>Se<sub>x</sub>. The composition of the ternary system is tuned to optimise the combination of carrier concentration and mobility to give a three-fold enhancement of the thermoelectric power factor at 300 K, and six-fold enhancement at 500 K, with respect to Bi<sub>2</sub>Te<sub>3</sub>. This improvement from the substitution of Te with Se is believed to be due to donor effects, as well as point defects caused by this substitution. <br/>
