| Research Abstract |
To develop an ultra-high speed switching device by means of molecular dynamics, fundamental properties of field electron emission from a single pentagon located at a tip end of multi-wall carbon nanotube. Current-voltage (I-V) characteristics of the pentagon with clean surface or adsorbed hydrogen molecule were measured by field emission microscopy. Switching actions with reproducibility were observed in the emission current for adsorption and desorption of a hydrogen molecule. Pulse irradiation of Nd;YAG laser with the wavelength on 532nm made possible to desorb a hydrogen molecule artificially without any damage of substrate pentagon.
