Abstract

C60 thin film crystals have been fabricated on the (001) surface of alkali halide substrates, KCl, KBr, and NaCl, and their structures have been studied. TEM observations show that the hexagonal close packing (hcp) with lattice parameters a = 10.0 Å and c = 16.3 Å and the face-centered cubic (fcc) with a = 14.2 Å coexist in the C60 thin film crystals. The ratio of hcp to fcc is very dependent on the kind of substrate and on the temperature during crystal growth. The coexistence of two phases is considered to be related to the difficulties in achieving alkali-doped M3C60 thin films.
