| Research Abstract |
Systematic molecular dynamics simulations with high-accuracy have been carried out for the (CO_2)_n (n=1-20) cluster impact onto carbon based surfaces with different morphology and density. Based on the simulations, energy concentration around the impact point contributing to thermal energy could properly evaluated depending on the target density, cluster size as well as the impact energy. The whole process was thermodynamically modeled assuming that sputtering was induced by thermal desorption upon the temperature rise around the surface due to the cluster impact.
