| Research Abstract |
We proposed a single-electron device that is analogous to the reaction-diffusion system, a chemical complex system producing various dynamic phenomena in the natural world. Our electrical reaction-diffusion device consists of a two-dimensional array of single-electron nonlinear oscillators that are combined with one another through capacitive coupling. Computer simulation revealed that the device produces animated spatiotemporal patterns of node voltages, e.g., a rotating spiral pattern similar to that of a colony of cellular slime molds and a dividing-and-multiplying pattern that reminds us of cell division.
