Thermoelectric Characteristics of Bulk Cr2Te3 with Low Lattice Thermal Conductivity

초록

In this study, we aimed to synthesize bulk Cr 2 Te 3 and evaluate its thermoelectric properties. Previously, Cr 2 Te 3 with alayered structure has primarily been synthesized in thin fi lm form for studies that focused on its magnetic properties. Theintrinsic 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 signifi cantly low lattice thermalconductivity of 0.31 W/mK at 673 K. Additionally, we explored the substitution of titanium and germanium at chromiumsites as a method to enhance thermoelectric performance, achieving a notable increase in the power factor.
