| 摘要 |
According to an embodiment of the present invention, a transistor includes a source electrode, a drain electrode, a graphene film formed between the source electrode and the drain electrode and having a first region and a second region, and a gate electrode formed on the first region and the second region of the graphene film via a gate insulating film. The graphene film functions as a channel. A Schottky junction is formed at a junction between the first region and the second region. The first region has a conductor property, and the second region is adjacent to the drain electrode side of the first region and has a semiconductor property.
