Abstract

We have investigated the decomposition ofC60molecules with low and high coverages on Si(100)(2×1) surface at elevated temperatures. We also investigated the decomposition of an isolatedC60molecule. We employed molecular-dynamics simulation using a model potential. It has been found thatC60decomposes on Si(100) surface after 1000 K in the case of low coverage (0.11), however in high coverage case (0.67),C60molecules decompose after 900 K. On the other hand, isolatedC60molecule decomposes after 7500 K, interestingly it shows a phase change from 3D to 2D at higher temperatures.
