Abstract

We report the characterization of interface formation between Au (Au) and pentacene, an organic material used as an active material in Organic Thin-Film Transistors, using x-ray and ultraviolet photoelectron spectroscopy (XPS and LIPS). XPS results indicate that there is no chemical reaction between Au and pentacene regardless of deposition order. UPS results indicate the presence of interface dipoles at both the pentacene/Au and the Au/pentacene interfaces. In addition there are indications of 'band-bending' at the Au/Pentacene interface.
