Outline of Final Research Achievements

For conventional semiconducting materials, band-gap engineering is realized by the composition control and doping. In this study, we focused on carbon nanotubes as a new material for band-gap engineering. We developed a strain device with MEMS technology, and we established the band-gap modulation technique with strain. We fabricated the CNT-strain devices, and we observed the emission wavelength shift under strain.
