STUDIES OF POLARON MOBILITY IN AGBR AT HIGH TEMPERATURES

The drift mobility of electronic polarons has been measured in AgBr from 50 to 300°K by a transit-time technique. Comparisons were made with the Langreth theory of polaron mobility at finite temperatures. Although the temperature dependence of the measured mobility agrees quite well with theory, there is a magnitude discrepancy between experiment and theory. © 1969 The American Physical Society.
