The Seebeck coefficient &agr;, electrical conductivity &sgr;, and thermal conductivityKdata are given for a number of Ag2Te specimens measured at room temperature. The maximum value observed for the figure of merit &agr;2&sgr;/Kwas 1.3×10−3°C−1. The relationship betweenKand &sgr; was linear, andKelcould be expressed approximately by (&pgr;2/3) (k/e)2&sgr;T.Kphwas found to be 0.72×10−2w cm−1°C−1. There was no evidence of an ambipolar diffusion contribution toK. It is suggested that the small energy gap (0.02 ev) previously determined in this compound could account for the absence of a measurable ambipolar diffusion effect, the degeneracylike behavior ofKel, and the relatively low values of the Seebeck coefficient.
