Hole mobilities of amorphous organic semiconductors were evaluated using the successive conduction (SC) method. Calculated mobilities for representative hole-transport materials were compared with experimental values obtained by the time-of-flight (TOF) method. The SC method reproduced the experimental mobilities with significantly lower computational cost than the conventional kinetic Monte Carlo (kMC) method.
