We investigate the non-equilibrium phenomena on material surfaces exposed to plasma by using molecular simulation. Those phenomena are related not only to the interaction between plasma and inside wall in fusion reactors, but also to the plasma application into the generation of nanomaterial. Since the processes on plasma facing materials often cannot be treated by existing simulation methods, we also have tackled the development of new simulation methods.
