摘要：

In the temperature range of 100-300 K, the electric (sigma) and thermoelectric (alpha(0)) properties of Ag2Se with an excess of Ag as high as similar to 0.1 at. % and Se as high as similar to 1.0 at. %, respectively, are investigated. From the data on sigma, alpha(0), and chi(tot) (thermal conductivities), the thermoelectric power alpha (0) (2) sigma and the figure of merit Z are calculated. It is found that alpha (0) (2) sigma and Z attain the peak values at room temperature and the electron concentration n a parts per thousand 6.5 x 10(18) cm(-3).
