DECOMPOSITION OF C-60 MOLECULES ON SI(111) SURFACE

We have investigated the adsorption and decomposition of C-60 molecule s on a Si(111) surface at elevated temperatures by using a molecular-d ynamics computer simulation. The potential energy function used in the calculations includes both two-and three-body interactions, which are represented by Lennord-Jones and Axilrod-Teller potentials, respectiv ely.
