| Research Abstract |
In this study, I studied optical properties of carbon nanotubes and carrier injection phenomena to carbon nanotubes, aiming to develop their potential as future optoelectronic devices. First, I analyzed the dependence of photoluminescence intensity on chirality of carbon nanotubes, and fount that dominant exciton relaxation process is non-radiative relaxation via multiple LO phonons. For light emitting devices, a technology to control the polarity of carriers injected into carbon nanotubes was developed, utilizing interface fixed charges introduced by a deposition of an insulator. I also realized simultaneous injection of electrons and holes into a carbon nanotube in p/n diode structure.
