| Outline of Final Research Achievements |
We have successfully observed the atomistic electric fields of single carbon atoms in a monolayer graphene by using our segmented-type detector in the scanning transmission electron microscopy. We have also identified that the atomistic electric fields of single Si dopants in a monolayer graphene is strongly depending on the local symmetry at the located atomic sites. Since dangling bonds are formed at the graphene edge, electric fields are enhanced towards a vacuum that enables to capture cations at the graphene edge. On the basis of our direct observations of atomistic electric fields, we conclude that nano-scale atomistic defects play important roles to enhance the catalytic reactions.
