Abstract
Measurements of the thermionic emission and electrical conductivity as a function of the temperature for fixed states of activation were obtained for each of the four barium chalcogenides. From the temperature dependences of these quantities the electron affinities were determined. The values obtained were 0.57 for BaO, 0.84 for BaS, 0.95 for BaSe, and 1.43 for BaTe. These values were found to be essentially independent of the state of activation of the samples.This publication has 12 references indexed in Scilit:
