Non-Equilibrium Electronic Systems Lab.

The Non-Equilibrium Electronic Systems Lab. (NEES) focuses on electronic systems driven far from equilibrium, where fluctuations, discreteness, and dynamics become essential elements of device operation. In NEES, we explore nanoscale devices as platforms for observing and controlling electron motion, aiming to uncover new physical principles and translate them into future electronic functionalities.
A distinctive feature of our laboratory is the integrated approach combining device fabrication, precision measurement, and theoretical modeling. While many studies on non-equilibrium phenomena are primarily theory-driven, we establish a unified framework that connects design, experiment, and simulation, enabling direct exploration and control of non-equilibrium electronic systems.

Research Overview

Control of Non-Equilibrium Phenomena

Non-equilibrium states lie at the heart of signal transport and operation in electronic devices. In our laboratory, we explore novel device physics by harnessing the stochastic motion of electrons, enabling the active control of non-equilibrium phenomena and the emergence of new functionalities.

Single-Electron Engineering

When electrical current is reduced to the level of individual electrons, their motion can be monitored in real time using a highly charge-sensitive sensor. Using such single-electron engineering, we investigate the active control and verification of non-equilibrium phenomena.
