| Outline of Final Research Achievements |
The purpose of this work is to establish a method for chirality and diameter control of semiconducting single walled carbon nanotubes (SWNTs) by irradiation and resonant absorption of ultra-short pulse laser, free electron laser (FEL) during CVD growth. As a result, a novel technique has been developed in order to prepare selectively semiconducting SWNTs with the uniform energy gap which is corresponding to the energy of irradiated FEL. Furthermore, we have tried to create nanoscale metal/semiconductor junctions (MSJ) as our wishes in a SWNT with its chirality changes by operating a FEL irradiation switch, and partially succeeded in preparation of MSJ in SWNTs.
