C-60 single crystals larger than one centimeter in size are grown with vapo
r method by nucleation control and by a proper time-dependent temperature p
rocess which allows only one nucleus growing larger and larger. X-ray diffr
action patterns exhibit the high quality of the sample. As an example of th
e applications of large single C-60 crystals, synchrotron radiation photoem
ission spectra are measured to investigate the fine structure of valence ba
nds of C-60 crystals.
