| Outline of Final Research Achievements |
Aiming at deeper understanding on nanoscale electric transport phenomena, especially transport dynamics of various aspects, we conducted computational studies mainly based on the density functional theory. Main achievements are as follows. (1) We have got a unified picture of the AC response of nanostructures. (2) We have succeeded in proposing high-performance field-effect transistor using the locally strained graphene channel and a new type of pure spin current generation device utilizing the quantum pumping effect and the edge spin polarization. (3) We have clarified laser-assisted field emission behaviors from graphene nanoribbons and silicene nanoribbons. (4) New method has been developed for the consideration of bias voltage. (5) We have succeeded in drastically speeding up the first-principles transport calculation code for large systems by adopting a novel algorithm.
