Laboratory Introduction

In our laboratory, we are working on electrical properties in two-dimensional atomic-layer materials and measurement/control of cutting-edge silicon quantum devices. We are developing new functional electronics, such as high-performance electronic and optoelectronic devices, sensors, and quantum computers, by exploring applications to new functions and principles.
