Abstract
Band gap structure of C60 epitaxial film is reported by using AC- photoconductivity measurement. The measurement clarify gap states by analyzing spectra two components of photocurrent and phase shift. A bias operation through semi-transparent Au electrodes has verified existence of Schottky barrier of about 2V. The temperature dependence of the spectra indicate that tail states correspond to structure change of C60 at around 250K.
