Outline of Final Research Achievements

We used graphene nanoribbon device to study the van der Waals (vdW) interaction tunability of the graphene－gas molecules based the time evaluation measurements of gas molecules adsorption/desorption on graphene. We used the first-principles calculations with the vdW density functionals to understand the microscopic details of charge transfer. We succeeded in controlling the vdW interaction between graphene and gas molecules complexes and reported the range of electrical tunability as a unique feature for each type of molecule. We studied graphene nano-electro-mechanical-system (GNEMS) switching operation for graphene-metal and graphene-graphene contacts and succeeded in reducing pull-in voltage to sub-1V.
