Influence of Copper Stoichiometric Composition and Compaction Method on Mechanical Properties of Cu<sub>x</sub>Se Thermoelectric Materials

This study investigates the structural and mechanical properties of Cu–Se-based thermoelectric materials with varying Cu:Se stoichiometries (1.8, 1.9, and 2.0). Phase composition was examined using X-ray diffraction (XRD), revealing a transition from a mixed α/β-phase in Cu:Se = 2.0 to a fully cubic...
