C60 and C70 fullerenes were vacuum deposited onto cleaved surfaces of NaCl and mica. Both C60 and C70 formed islands during a first stage of growth, indicative of the Volmer-Weber growth mode. The crystal structure of C60 films on NaCl was f.c.c. with abundant lamella twinning and stacking faults. The structure of C70 films on NaCl was also predominantly f.c.c. when the substrate was held above about 370 K. The films on NaCl were polycrystalline. On mica, single-crystal epitaxial films were formed for both C60 and C70 with the orientation relationship (111)C60 or C70∥(001)mica.
