From: Flexible power generators by Ag2Se thin films with record-high thermoelectric performance
Temperature-dependent (a) electrical conductivity σ, (b) Seebeck coefficient S, and (c) determined S2σ. d Measured x-dependent carrier concentration n and mobility μ at room temperature. e Calculated x-dependent effective mass m* and deformation potential Edef at room temperature by a single parabolic band (SPB) model. Temperature-dependent (f) thermal conductivity κ. g x-dependent electronic and lattice thermal conductivities (κe and κl) at room temperature. h Temperature-dependent ZT. i Comparison of calculated and experimental ZTs as a function of n. The calculated data are from the SPB model.
