Abstract
Drift mobilities of electrons in biphenyl in the a, b, and c′ crystal directions have been measured by the pulsed photoconductivity method and are 0.42, 1.25, and 0.51 cm2/V sec, respectively, at room temperture. For the a and c′ crystal directions these mobilities show a T−1.0 dependence, and a T−1.25 dependence for the b direction. No hole photocurrents were observed. The mechanisms of carrier transport and generation are discussed in terms of current theories.Keywords
