| Outline of Annual Research Achievements |
Graphene and CO2, N2 van der Walls (vdW) complexes interaction was clarified by the first-principle study and experimental results. Signature of the weak dopants and strong dopants were established by the tuning of the change transfer under a range of electric field. vdW interaction tunability of the graphene－CO2 complex was elucidated by combining the first-principles calculations with vdW density functionals and the time evaluation measurements of CO2 molecules adsorption/desorption on graphene under an external electric field. The field-dependent charge transfer within the complex unveils the controllable tuning of CO2 from acceptor to donor. Meanwhile, the configuration of the adsorbed molecule, the equilibrium distance from graphene and O－C－O bonding angle, is modified accordingly.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
We have divided this research work into First-principles simulations and Experimental works. First-principles simulations help us to understand the experimental works. We are planning for more experimental and simulation works.

| Strategy for Future Research Activity |
The naturally formed chromium oxide at the contact interface is being effectively exploited to prevent the formation of chemical bonds between the graphene and the metal electrode. For this purpose, Chromium - graphene GNEMS device is being fabricated. At first, these devices switching characteristics will be evaluated. Also, switching operations at different pressure levels will be evaluated. Once these devices are realized then we will study the vdW interaction induced Electromechanical motion of suspended Graphene beam in GNEMS devices. Fundamental role of molecules vdW interaction in Electromechanical movement will be characterized. In order to reduce the Pull-in voltage of GNEMS, CO2, NH3, N2, and H2 -graphene vdW complexes induced electromechanical movement will be evaluated.
