Recruitment

We are actively recruiting motivated students, who are interested in the science of low-dimensional nanomaterials. We especially welcome those with an interest in the field and a passion for pioneering a new field, regardless of experience. If you are interested in pursuing a Ph.D. in our group, please contact us (KITAURA.Ryo@nims.go.jp). We can accepte students through the Joint Graduate School Program in NIMS. We are recruiting postdocs as well. We can help you to prepare the application form for JSPS Postdoctoral fellowships.

Research Interest

Electrons and phonons confined in low-dimensional nanostructures respond differently to external stimuli, leading to phenomena that are distinctly different from those in bulk materials. Low-dimensional nanostructures, therefore, provide a fascinating platform for exploring novel phenomena. In order to explore the possibilities of low-dimensional nanostructures, our research activities have focused on

Fabrication of low-dimensional nanostructures using advanced thin film growth techniques
Structural analysis and local electronic structure characterization using microscopy techniques
Exploration of novel phenomena through optical/electronic property measurements

We work on various one- or two-dimensional nanomaterials, including carbon nanotubes, graphene, transition metal dichalcogenides and their heterostructures. The growth of high-quality samples, the fabrication of nanodevices, and the optical/electronic characterization are the core of our research. Our goal is to open up the next generation of nanoscience with open-minded thinking that is not limited by conventional frameworks such as physics and chemistry.
