| Outline of Final Research Achievements |
In this research, the shot noise measurement system and conductance measurement system for single-atomic/molecule junction were established with a view to clarify the electric property of single-atomic/molecule junction. The established measurement system was applied to the single-atomic/molecule junctions. Especially, the gold atomic contact in the presence of pyrazine molecule showed interesting phenomena.
Gold atomic contact was fabricated using mechanically controllable break junction technique. The shot noise measurements together with the conductance measurement verified that gold atomic contact has the one conductance channel with perfect transmission without pyrazine; on the other hand, it has additional channels with pyrazine. The presence of the additional channel is explained by the interaction between pyrazine and gold.
