Abstract

The spectral photoresponse of Al/pentacene Schottky junction photodiodes and optical absorption spectra of pentacene films thermally evaporated on glass were measured. The photoelectric response exhibited the genuine highest occupied molecular orbital (HOMO)-lowest unoccupied molecular orbital (LUMO) transition at 1.97 eV. It was shown that the interband absorption peaks were identified in the optical absorption spectra. The HOMO-LUMO gap energy of 1.97 eV and the fundamental exciton binding energy of 0.15 eV for thin solid pentacene were determined by comparing the complementary measurements.
