Two-dimensional transition metal dichalcogenides (TMDCs) have relatively good electrical conductivity and relatively low thermal conductivity among all two-dimensional materials, which indicates their potential for thermoelectric energy conversion applications. The existing studies on of few-layer TMDCs, such as MoS2 and WSe2, have shown improved thermoelectric performances compared to their bulk and their peak thermoelectric power factor can exceed that of a commercial bulk Bi2Te3 . In this study, we fabricate devices from mechanically exfoliated TMDCs (for example MoTe2) and aim to optimize their thermoelectric properties by varying parameters, such as temperatures, back gate voltages and substrates.
