single crystals. The (111) and the (001) faces of C60 single crystals were illuminated with photons with energies below the band gap (generation of Frenkel-type excitons) or above the band gap. In the case of sub-band-gap illumination, reconstructed surfaces formed on the crystals. The reconstruction was represented by fringes running in the [11\(\)] and [0\(\)0] directions on the (111) and (001) surfaces, respectively. As a result of supra-band-gap illumination, however, there appeared only cracks, without any fringes, which were oriented in directions characteristic of each face. The results suggest that the photo-induced surface reconstruction of C60 single crystals is induced via the recombination of Frenkel-type excitons.
