Abstract

In this work, we investigated the material properties of pentacene films with XRD and AFM analyses as it were annealed from 25 to 150 °C in N ₂ ambient. Electrical characterization of the films was also performed by transfer length method (TLM) at each temperature. These results were then correlated with the Fermi level pinning phenomenon in Al- and Ti-pentacene junctions. For both junctions, it was found that as the surface quality of the pentacene films changed with increase in annealing temperature, the hole-barrier heights (h-BH) that were modulated by Fermi level pinning were effectively reduced.
