Research Abstract

In this work, we proposed a quantum-dot device that imitated the dynamics of reaction-diffusion systems. A reaction-diffusion system (RD system) is a chemical system where chemical reactions and material diffusion coexist in a nonequilibrium state. There are various RD systems in nature, and a variety of dynamic, self-organizing natural phenomena can be explained using the concept of RD dynamics. Constructing an electrical analog of reaction-diffusion systems will enable us to generate artificial biodynamics on a LSI chip and develop bioinspired information-processing systems.
We proposed constructing an electrical analog of RD systems, i.e., an electrical RD system consisting of quantum-dot circuits. An RD system can be considered an aggregate of chemical nonlinear oscillators interacting with one another, so we can construct electrical RD systems by using electrical oscillators instead of chemical ones. We used, as the electrical oscillator, a quantum-dot circuit that produced nonlinear oscillation caused by the Coulomb blockade phenomenon. The action of diffusion in RD systems can be imitated by capacitive coupling between the oscillators. By arranging coupled oscillators into a network, we designed a quantum-dot RD system. We showed through computer simulation that the system produced electrical dissipative structures, or animated spatiotemporal patterns of node potential in the circuit, which was a characteristic similar to that in chemical RD systems.
