This work demonstrates the thermoelectric (TE) performance of the cavity-free thermoelectric generators (TEGs) using GeSn and Si wires. In the cavity-free TEG, the TE power generated from a unit area is enhanced by shrinking the wire length (Lwire) by applying a steep temperature gradient. GeSn is one of the attractive TE materials due to its low thermal conductivity and high-power factor. In this work, we compared GeSn wires with Si wires in cavity-free planar structure focusing on the scalability.
