Abstract

This work reports the high performance micro-thermoelectric generators (TEGs) based on metal-doped electrochemical deposition. Ultra-thick (2 mm-thick) and compact electrodeposited thermoelectric material have been successfully synthesized with high Seebeck coefficient sim -143 mu mathrm{V}/mathrm{K}, high electrical conductivity ∼970 S/cm and low thermal conductivity ∼ 0.6 W/mK. As the result, the performance shows Figure of merit ZT=1 at room temperature, which is one of key factor for high performance TEG. Two kinds of TEG including pure Bi2Te3 and metal doped Bi2Te3 were fabricated, evaluated and compared.
