| Outline of Final Research Achievements |
We study skyrmion excitations in graphene by means of the electronic transport measurement. However, due to the lack of sample quality, we could not observe skyrmion excitations from the quantum Hall effect. However, we measured the relationship between the universal conductance fluctuation and the weak localization effect. The experimental results indicate that the two phenomena are identical. The results can be applied to conductance fluctuations in other systems. We also developed suspended graphene devices, in which a large increase in the mobility can be expected.
