| Outline of Final Research Achievements |
Growth processes and mechanisms of carbon nanowalls (CNW) were investigated. Employing plasma diagnostic techniques and surface composition and structure analyses methods, we developed compact radical source, which can be installed to “Reaction science high-voltage scanning transmission electron microscope” (Nagoya University). And, in-situ observation technique of nanographene nucleation and growth processes at the CNW growth by plasma-enhanced chemical vapor deposition method. Surface composition change and biding structure change were also investigated using X-ray photoelectron spectroscopy. Effects of fluorine and hydroxide radicals exposed to CNW surfaces were clarified. Selective growth of CNW of patterned metal electrodes were also studied.
