Welcome to the Takenobu Lab Website

Our research focus on p-electron materials, e.g. organic and nano-carbon materials. Our aim is to understand physical properties of these materials and to explore their novel functional devices. The current research interests include investigating transport and optical properties of carbon nanotubes, atomically thin materials, and conducting polymers. We also focus on device applications using these materials, such as transistors, thermoelectric devices, light-emitting (photo-detecting) devices, and lasers. If you are interested in our group, please contact us.

We always welcome domestic/international JSPS research fellows. Please see the following website for further information: more info
