报告摘要：

Due to the remarkable progress of computationalsciences including first principles calculations, we can predict the physicalproperties of new materials and device characteristics by theoreticalcalculations. For example, we can well reproduce surface reconstructions at theatomistic level, and we can predict the importance of oxygen vacancies inhigh-k HfO2 oxide dielectrics based on the first principles calculations.Actually, first principles calculations are treated as crucial tool fordesigning future micro-electronic engineering in the present days.

In this presentation, we will show the newscientific findings which gives great insight to modern micro electronicsengineering by showing some recent our activities given by first principlescalculations. We discuss the importance of computational sciences fordeveloping future micro electronics devices by showing the example ofsuccessful results of first principles calculations such as design of high-kLSI, operation mechanisms of modern memory devices including charge trapmemories (MONOS) and resistance random access memories (ReRAM).
