Hybrid Simulations for Desinging of Nano-Interfacial Structures

There is growing demand to perform dynamic, atomistic computer-simulation of nano-scaled interfaces. For dynamic simulation of interesting processes at the nano-interfaces, we have been developing the hybrid simulation schemes by concurrently coupling the quantum description as the electronic density-functional theory and the classical description as the classical molecular dynamics. A quantum (QM) region composed of a relatively small number of atoms, is embedded with the novel buffered-cluster method in a classical (CL) region of atoms interacting through an empirical inter-atomic potential. The hybrid QM-CL simulation scheme is applied to various kinds of nano-processes including implantation of oxygen atoms to a Si slab relating to SIMOX technology.
