Abstract
Modifications induced by laser heating of C60 single-crystal surface under different conditions are examined by scanning electron microscopy. The fullerite surface is etched in the presence of oxygen, whereas no substantial change is seen under inert atmosphere. The fragments, obtained after the oxygen-induced disintegration of fullerene, form a material with a nanostructure similar to amorphous carbon. Three-dimensional microstructures are produced depending on laser annealing conditions. Oxygen in the irradiated region substantially increases, according to energy dispersive x-ray spectroscopy of the surface.
