| Outline of Final Research Achievements |
I am aiming at developing a surface creation process in water to flatten a Ge surface free from metallic contamination. In this research period, I have obtained the results shown below.
(1) I confirmed that nitrogen (N) atoms can be doped in graphene by a thermal treatment in a mixed NH3/Ar gas. (2) I performed electrochemical measurements. It was demonstrated that the catalytic activity of N-doped graphene to enhance O2 reduction reactions is in between those of Pt and a carbon bulk. (3) Graphene particles were deposited on a Ge surface, and this sample was immersed in water with dissolved O2 molecules. I found that a Ge surface around the deposited graphene particles was selectively etched. This is owing to the catalytic activity of graphene.
These results are important and essential to continue further experiments.
