Research Topic

Implementation of information processing function on single-molecule-integrated networks and improvement of its reliability

Research Aim

In creation of single-molecule-based electronic systems, key issue is logical representation and operation scheme that utilizes the function and small size of individual molecules. The objective of this study is to find a Boolean logic operation scheme and architecture suitable for single-molecule networks, build the basic technologies for their implementation, and also find an approach to improve operation reliability of the molecular devices and systems.

Role and Need in the Group

Our role is a designer of the molecular architect. Our study contributes to design and construct a "building" of a single-molecule-based information processing system utilizing advanced single-molecule sciences and technologies of this area.

Research Content

We make a bridge between Boolean logic representation and single-molecule networks through graph-based logic architecture which has been applied to quantum nanodevice circuits and 3-branch junction-based nonlinear devices. On the basis of the advanced single-molecule technology and design of this area, we create useful functions and structures for constructing logic circuits. We cause stochastic resonance, a phenomenon in which the response to a weak signal is optimized by noise, on a molecule and develop the technology for applying the phenomenon to logic operation in the molecular system.
