Outline of Final Research Achievements

Microspectroscopy has been performed on chirality-identified suspended carbon nanotubes within field-effect devices, and response of excitons in electric fields has been investigated. Simultaneous photoluminescence and photoconductivity spectroscopy have revealed spontaneous exciton dissociation and field activation of dark excitonic states, and Stark effect has been directly compared with theory. Formation of trions has been observed under an application of gate voltages, while it was found that square-wave gate voltages can induce optical pulse trains. Light emitting diodes using split gates has also been investigated.
