Outline of Final Research Achievements

In this work, we studied the electronic properties of nanoscale interfaces consisting of nanoscale carbon materials, such as fullerenes and carbon nanotubes, and inorganic semiconductors. In particular, we elucidated the possibility of unusual physical properties arising from the nanoscale interfaces. Our study showed that the nanointerfaces lead to an unusual electron state that floats between the constituents with free electron nature. In addition, we also found that the induced electric field in the nanoscapcing depends on the electronic structures of constituent materials.
