Abstract
Band gap structure of C-60 epitaxial film is reported by using AC-phot
oconductivity measurement. The measurement clarify gap states by analy
zing spectra two components of photocurrent and phase shift. A bias op
eration through semi-transparent Au electrodes has verified existence
of Schottky barrier of about 2V. The temperature dependence of the spe
ctra indicate that tail states correspond to structure change of C-60
at around 250K.
