| Outline of Final Research Achievements |
The purpose of this project is to resolve problems quantum mechanically in the field of power-semiconductor science based on the computics approach. In methodology viewpoints, we have newly developed order-N orbital-free density-functional-theory (OFDFT) scheme using the neural network, and demonstrated its validity and the higher performance compared with our RSDFT code which is the Gordon-Bell-prize winner in 2011. In semiconductor-science viewpoints, we have unveiled atomic processes in epitaxial growth of GaN and SiC, and microscopically identified carrier traps at the interfaces with gate insulators, using the RSDFT and OFDFT schemes. The obtained achievements are in public as 29 original papers in major science journals and as 11 invited talks in the inter- and intra-national conferences.
