摘要

Carrier mobility is an important parameter in determining device performance in electronics and the values of the electron and hole mobilities for organic semiconductor thin films are known to be rather low. This work studied some reported data on electron and hole mobilities in the literature and analyzed them using a barrier height modulation model and the better known "disorder" model [4]. Our results indicated that the physics behind the two models could be correlated and both pointed to some limiting values pertaining to the localization of the carriers. By comparing the results with an evaluation of the potential profiles across a given cross section of the monomer backbone (for OC₁C₁₀PPV) with different subgroups, we were able to deduce that the "localized" states were not directly associated with the energy bands. This provides an opportunity to increase the carrier mobility to its upper limit by applying a transverse bias
