Outline of Final Research Achievements

Toward an ultimate information processing system integrating functional single molecules, we investigated and developed single-molecule technologies that make it possible to correctly operate under indispensable fluctuation, including information processing scheme and architecture based on single molecules, and a novel nonlinear dynamic processing approach providing reliable operation. We achieved basic Boolean logic gates using a simple graphene-based three-terminal nanojunction device, a novel detection technique for molecular charge dynamics and its analysis, amoeba-inspired solution search computer for solving combinational optimization problems that works exploiting temporal fluctuation. Furthermore, we found out a new model of stochastic resonance in a bistable system where the response to weak signal is enhanced by adding noise and particularly this mechanism clearly appears in nano and molecular scale systems.
