Crystalline Structure-Dependent Mechanical and Thermoelectric Performance in System
Temperature dependences of (a) electrical conductivity and (b) Seebeck coefficient for (, 0.1, 0.2, 0.3, 0.4, and 0.45). (c) Temperature dependence of power factor (PF) for (, 0.1, 0.2, 0.3, 0.4, and 0.45). (d) Seebeck coefficient , (e) Hall carrier mobility , and (f) PF as a function of carrier concentration for at 300 K. The dashed lines represent the theoretical curves based on the single parabolic band (SPB) model with a dominated scattering mechanism by acoustic phonons. The data for Ag2Se and Ag2Se0.5S0.5 reported before are added for comparison [21, 26–29].
