| Research Abstract |
We investigated the fabrication of nanostructures and its quantum transport in low-dimensional graphite crystals such as two-dimensional graphene and one-dimensional carbon nanotube structures toward future quantum nanodevices with novel functions. In this research, we established the nanofabrication process to control the structure of low-dimensional graphite crystals, and fabricated a coupled quantum dot device comprising two lateral quantum dots by applying a nanofabrication process to the graphene. Our experimental results indicate that the number of electrons in a quantum dot, the coupling state between the electrons, and other properties can be controlled artificially using external voltages in the fabricated quantum devices. Because this research shows the potential for development of integrated nanodevices using a new carbon material, it is expected to contribute to progress in the development of nano quantum devices.
