| Outline of Final Research Achievements |
In this research project, we have investigated the electronic and optical properties of atomically-thin materials such as graphene and transition metal dichalcogenide (TMDC) monolayers based on the theoretical modeling methods and first-principles calculations. Main findings in this project is following: [1] unveiling of peculiar emergence mechanism of localized magnetic states at the graphene domain boundaries [Sci. Rep. (2015)], [2] finding of stable Dirac cones in CaSi2 and their momentum shift [Phys. Rev. B (2015)], [3] valley polarization of carbon nanotubes under circularly-polarized Irradiations [Appl. Phys. Exp. (2016)], [4] theoretical propose of new topological phases without a Berry curvature [Phys. Rev. Lett. (2017)]. Our work will serve for designing new class of electronic devices on the basis of atomically-thin materials.
