The structure of condensed C60 and C60/Bi
films has been studied. The films were grown at the ratio of Bi
atoms to fullerite molecules in the composite films not more than
1:10 on orienting substrates heated to 400-500 K. Formation
conditions have been determined for perfect hcp films. The segregation
of Bi atoms in the fullerite lattice has been found to take place
as nanosize aggregates giving no diffraction contrast. The absence
of reflections with a symmetry distinct from that of C60
lattice is explained by that Bi atoms are arranged within octahedral
voids of the fullerite hcp lattice.
