Charge transport in amorphous molecular materials

摘要

Charge carrier drift mobilities of a series of hole-transporting amorphous molecular materials have been determined by a time-of-flight method. Electric-field and temperature dependencies of carrier mobilities have been analyzed in terms of the disorder formalism, and charge transport in amorphous molecular materials is discussed in relation to molecular structures. Hole-transporting amorphous molecular materials with high mobilities of the order of 10-2cm2V-1s-1 have been developed.
