Public Lecture: Solitons — Collective Electron Waves for Ultra–Low–Power Computing — Insights from Advanced Characterization
Information
We witness that the silicon device technology, the foundation of current information civilization, is close to its end with the limit of device miniaturization and the explosive growth of the energy consumption in processing information. While post-Si device architectures such as TMDC devices are under active development, technological and fundamental breakthroughs are requested for devices consuming much less energy. In the physics point of view, it is a challenge to find quasi-particles and their device platforms, that can carry information in higher density and without energy dissipation. While there are a few candidates such as photons, Copper pairs, various quantum Hall currents, spin currents, and excitons, we have proposed topological solitons in 1D and 2D materials as one new direction. Topological solitons can deliver multi-level information without significant energy loss. In 2013-2017, we made it possible to microscopically observe individual topological solitons in 1D materials for the first time since its discovery in 1979. Until 2022, we developed this research to secure model 1D systems for a few different types of microscopically accessible solitons and to track their motions. Our recent work demonstrates the manipulations of solitons and their interactions, which may open a way toward soliton technology in electronic systems.
