| Outline of Final Research Achievements |
I studied electronic properties of topological monolayer materials such as silicene, germanene and stanene. I revealed various topological phase transitions induced by electric field and photo-irradiation, and proposed many topological devices such as a topological field-effect transistor. I determined the band
structure of the group-V and the group-III monolayer materials. Especially, I revealed the edge states of phosphorene, which is a monolayer material made of phosphorus. I also calculated the band structure of arsenene, which is a monolayer arsenic and aluminene, which is a monolayer aluminium, by first-principles calculations.
Furthermoe, I studied non-equilibrium dynamics of skyrmions, which are topological solitons in magnets.
