Development of Nano-device simulator and application to low-power circuit

点击翻译按钮获取中文摘要

Development of time-dependent first-principles electronic structure simulation program is performed for analysis of high speed electronic devices. The railway algorism and the norm-conserving pseudopotential method are implemented into the program for high speed and high precision calculation. By testing the response of electronic structure of an atom or a molecule and observing the resonance of electronic structure with the input electronic field, the validity of the program is evaluated.
