Thermoelectric Characteristics of Bulk Cr2Te3 with Low Lattice Thermal Conductivity

In this study, we aimed to synthesize bulk Cr2Te3 and evaluate its thermoelectric properties. Previously, Cr2Te3 with a layered structure has primarily been synthesized in thin film form for studies that focused on its magnetic properties. The intrinsic layered structure of Cr2Te3 can contributes to its low lattice thermal conductivity. Our experimental results confirmed the successful synthesis of a homogeneous single-phase specimen and revealed a significantly low lattice thermal conductivity of 0.31 W/mK at 673 K. Additionally, we explored the substitution of titanium and germanium at chromium sites as a method to enhance thermoelectric performance, achieving a notable increase in the power factor. [GRAPHICS] .
