| Research Abstract |
Owing to extremely high mobility, carbon atomic layer, graphene, is a promising candidate for future high-speed electronic material. On the other hand, graphene device has a problem that the field-effect mobility is severely degraded for a shorter channel. This is due to carrier injection from electrode metals. In this project, we investigated the influence of electrode connection in details for several metal species. Besides, we succeeded in removing the influence of electrode connection by inserting amorphous carbon layers between the graphene film and electrodes.
