DOI: 10.1021/acsami.2c00437
Abstract: For practical applications of copper selenide (Cu2Se) thermoelectric (TE) materials with liquid-like behavior, it is essential to determine the structure-property relations as a function of temperature. Here, we investigate β-Cu2Se structure evolution during uniaxial compression… read more here.
