| Research Abstract |
Graphene is an ultimate 2D form of material and thus has been noticed in terms of its unique nano properties. However, it has no band-gap and thus is unable to apply for switching devices. Therefore, band-gap opening is a significant issue for this purpose. Many methods have been reported to open band-gap and among them nanoribbons are recognized to be especially important because of relatively large gap formation. We here tried to selectively grow graphene on SiC nano-surfaces, including periodic step/terrace structures, and succeeded in graphene nano ribbon formation. Electronic structures at K-points were examined and found clear band-gap opening.
