Abstract

The electronic structures of pentacene and C₆₀ interfaces were investigated using ultraviolet photoelectron spectroscopy (UPS) and X-ray photoelectron spectroscopy (XPS). The magnitudes of measured interface dipole were 0.11 eV and 0.07 eV for the C₆₀ deposited on pentacene (C ₆₀/pentacene) and the pentacene deposited on C₆₀ (pentacene/C₆₀), respectively. The obtained C 1s spectra on these samples show that no significant chemical bonds at the interface. The offsets of the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) at the C₆₀-pentacene interface were 1.29 eV and 0.89 eV for C₆₀/pentacene/Au, while for pentacene/C ₆₀/Au they were 1.5 eV and 1.1 eV. In this paper we present the complete energy level diagrams of C₆₀/pentacene/Au and pentacene/C₆₀/Au.
