| Abstract Scope |
Thermoelectric materials have attracted significant attention due to their potential application in power generation and refrigeration systems, because they can convert thermal energy into electric energy from waste heat recovery. Thin thermoelectric films can be used to create thermoelectric generators, where the power they create does not result in any additional emissions. PbTe, PbSe and Sb2Te3, Bi2Te3 present excellent choices for thermoelectric energy harvesting devices. This study investigates Seebeck coefficient measurements of these thermoelectric thin films synthesized by Atomic Layer Deposition (ALD) technology. The efficiency of TE materials is expressed by the dimensionless thermoelectric figure of merit, ZT = S2σT/κ, where S is the Seebeck coefficient, σ is the electrical conductivity, and κ is the thermal conductivity. Because the crucial Seebeck coefficient factors directly into the equation to determine ZT by the power of two, it is imperative to optimize the thermoelectric thin film material for maximum Seebeck coefficient. |
