Introduction

Focusing on the unique structures and properties of surfaces and interfaces of materials, we are engaged in evaluating various materials such as metals, semiconductors, oxides, organic thin films, and adsorbed molecules. Through single-atom and single-molecule scale analysis using scanning probe microscopy, we aim to gain insights that are key to elucidating catalytic reaction mechanisms and developing next-generation devices.
