ReaxFF SiO Reactive Force Field for Silicon and Silicon Oxide Systems

To predict the structures, properties, and chemistry of materials involving silicon and silicon oxides; interfaces between these materials; and hydrolysis of such systems, we have developed the ReaxFFSiO, reactive force field. The parameters for this force field were obtained from fitting to the results of quantum chemical (QC) calculations on the structures and energy barriers for a number of silicon oxide clusters and on the equations of state for condensed phases of Si and SiO2 from QC. We expect that ReaxFFSiO will allow accurate dynamical simulations of bond breaking processes in large silicon and silicon oxide systems. ReaxFFSiO is based closely on the potential functions of the ReaxFFCH reactive force…
