报告内容简介：

By the recent advancement of nano-technology, “chemical reaction” at nano-scale significantly affects the macro-scale property and performance of MEMS, semiconductor and tribology systems, and then the electronic-level control of the chemical reactions is essential even in the MEMS, semiconductor and tribology systems. Especially, electronic-level understanding of the multi-physics phenomena including the “chemical reaction” and “friction, impact, stress, fluid, photon, electron, heat, electric fields etc.” is very important. Previously, continuum simulations such as finite element method have been employed for the investigation on the multi-physics phenomena without chemical reactions at macro-scale. However, quantum chemical approach is essential for the elucidation of chemical reactions. Hence, we recently succeeded in the development of new multi-physics simulator based on our original first-principles and tight-binding quantum chemical molecular dynamics methods, which enables us to simulate the multi-physics phenomena including “chemical reaction” and “friction, impact, stress, fluid, photon, electron, heat, electric fields etc.” We also developed multi-scale simulator to clarify the effect of “chemical reaction” at nano-scale on the macro-scale property and performance of MEMS, semiconductor, and tribology systems (Fig. 2). Moreover, we applied the above simulators to a wide variety of energy problems, environmental problems, and nanotechnologies.
