| Research Abstract |
In order to electrically, magnetically, and optically functionalize single-walled (SWNT) and double-walled (DWNT) carbon nanotubes, methods of diffusion plasma chemical vapor deposition (CVD) and plasma-ion injection were developed, applied, and made the best use of. As a result, we succeeded in the structure-controlled growth of SWNTsuch as narrow-chirality distributed growth, creation of various charge- /spin-exploited atoms and moleculesencapsulated SWNT and DWNT, and universal control of SWNT/DWNT semiconducting properties. Moreover, we demonstrated the principles of novel surrounding-stable nanodevices such as high-performance nagative differential resistance element, ultimate pn-junction diode, semiconductor-magnetism fusion element, electrooptic fusion (optoelectronic switch, photoelectric conversion) element, and n-type thin film transistor.
