We have measured drift mobilities in vacuum deposited films of tris(8-quinolinolato)aluminum (Alq(3)), a triphenylamine derivative (TPD) and a naphtyl-substituted benzidine derivative (alpha-NPD) using a time-of-flight (TOF) technique. The hole mobilities of TPD and alpha-NPD are about two orders of magnitude higher than the electron mobility of Alq(3). This implies that the current density versus applied voltage characteristics is dominated by the electron mobility of Alq(3) rather than the hole mobility of TPD or alpha-NPD in double-layered devices ITO/TPD or alpha-NPD (50 nm)/Alq(3) (50 nm)/MgAg.
