Description
In the temperature range of 100-300 K, the electric (σ) and thermoelectric (α0) properties of Ag2Se with an excess of Ag as high as ∼0.1 at. % and Se as high as ∼1.0 at. %, respectively, are investigated. From the data on σ, α0, and χtot (thermal conductivities), the thermoelectric power α02σ and the figure of merit Z are calculated. It is found that α02σ and Z attain the peak values at room temperature and the electron concentration n ∼ 6.5 x 1018 cm-3.
