Design of “bubble-inspired single-electron circuit” mimicking behavior of bubble film

Abstract

We propose a novel single-electron (SE) circuit with unique information-processing that mimics the behavior of bubble film, i.e., a “bubble-inspired SE circuit.” It is known that the behavior of bubble film can be assumed to solve the shortest Steiner problem. In this study, we focus on the behavior to design a novel SE circuit. For this, there are three important points, we believe, for mimicking the behavior for the circuit: 1) the film gradually shrinking, 2) the film stopping shrinking when reaching points like pillars, and 3) films stopping shrinking when they collide with each other. We here designed and tested our SE circuit. By computer simulation, we confirmed that the designed circuit displayed the three processes correctly as desired. Therefore, the “bubble-inspired SE circuit” we designed has the potential for novel information processing.
