| Outline of Final Research Achievements |
The gap between material properties and device performances of 2D materials inhibits high performance of 2D material-based devices. To solve this gap, we performed studies on a development of operando x-ray spectromicroscopy and its application to novel devices. As a result, we established the method to probe electronics states of surfaces and interfaces of devices with a high spatial resolution (70 nm in lateral direction). By using operando x-ray spectromicroscopy, we developed a novel graphene transistors that enables to the drain current saturation. Furthermore, we observed electronic states of Molybdenum disulfied FET microscopically. Finally, we extended our research into other novel devices, such as topological insulators.
