Abstract

We report investigations on a Pentacene thin film as a component for active layer of Organic thin film transistors. Pentacene film was deposited by Organic Molecular Beam Deposition(OMBD) and Al electrode was deposoted by vacuum evaporation. Electrical characterization of Pentacene films were measured by the three-terminal contact resistance methods, as the results contact resistance between pentacene films and the Aluminium electrode is 5.064G$\Omega$. The Al contact with the pentacene shows the bottom contact resistance. From the current-voltage characteristics, electrical conductivity of the Pentacene film is found as ~ 10$^{-4}$ /cm. physical characterization of pentacene films were measured by UV-spectrum and Cyclic-Voltammetry method.
