Application of carbon nanotube electodes with nano-scale gap and its fabrication method are reviewed. Contact resistance in nano-scale molecular electronics or organic electronics is serious issue to be solved for operation of future electronics. So far, conventional metal electrodes are widely used for the nano-device researches. Here, we proposed to use the carbon nanotube, and a pentacene nanocrystal transistor with carbon nanotube electrodes as a nanosize source and drain was fabricated. In the device fabrication, the evaporated pentacene selectively grew around the nanotube electrodes. This may be caused by the common nanounit combination of the carbon six-membered ring contained in the pentacene and the nanotube. The nanotransistor showed controllable transistor operation at room temperature and Coulomb blockade oscillations at 4.2 K in gate voltage characteristics.
