Chalcogenides of IV-VI and V2-VI3 families have attracted the attention of the scientific community for decades since some of the members of these families, recently named incipient metals , feature extraordinary properties. The property portfolio of these incipient metals includes soft and anharmonic bonds, relatively small band gaps, moderately high electrical conductivity, high Born effective charges, high dielectric constants, high thermoelectric figures of merit, and high optical absorption [1-4]. These extraordinary properties make them ideal as phase change materials (PCMs) in data storage applications, as highly efficient thermoelectric and photovoltaic materials for green technologies, and also as topological materials for quantum computation.
