In recent years, semiconductor materials based con chalcogenides have receive great attention owing to their wide applications in numerous fields. In addition, chalcogenide elements are earth abundant, cheap and non-toxic. One of the main potentials applications for chalcogenide-based semiconductor is the thermoelectricity. Although compounds here studied (concretely SnX and SnX2 with X = S, Se, Te) have been extensively characterized, theoretical studies on the relationships between the electronic structure, dimensionality and thermoelectric features are very scarce. Herein, we propose a comprehensive study on the electronic structure and thermoelectric properties in chalcogenides-based semiconductor materials by using first-principles calculations combined with the Boltzmann transport theory.
