The objective of my research is to analyze and to understand the electron transport properties of various materials for the applications to novel high-performance electron devices, such as transistors, solar cells and others. Therefore, I have developed a large-scale quantum transport simulation method, called as "Time-dependent Wave-packet diffusion (TD-WPD) method".
TD-WPD method is based on the full treatment of quantum theory and computes the quantum transport properties for various huge systems with up to 10^8 atoms, which enables me to treat electron transport problems from classical diffusion regime to quantum ballistic regime. In this methodology, I calulcate the time-evolution of electron wavepackets and evaluate the conductivity, the mobility and the mean free path within the Kubo formula.
