The purpose of this study is to elucidate the mechanisms of various processes and phenomena at solid surfaces and interfaces by using various means including newly developed sum-frequency generation microscopy, scanning tunneling microscopy, theoretical simulations, and time-resolved second harmonic and sum-frequency generation spectroscopy. This study mainly focused on reactions at oxidized silver surfaces, photo-reduction at gold nanoclusters, carrier distributions at the interface between organic semiconductor and dielectrics, coherent surface phonon excitation at alkali metal adsorption systems, and vibrational energy transport in nanometer-thick layers on metal surfaces.

本研究的目的是利用新开发的和频发生显微镜、扫描隧道显微镜、理论模拟、时间分辨二次谐波和和频等多种手段，阐明固体表面和界面上各种过程和现象的机制。一代光谱学。本研究主要集中在氧化银表面的反应、金纳米团簇的光还原、有机半导体和电介质界面的载流子分布、碱金属吸附系统的相干表面声子激发以及金属纳米厚层中的​​振动能量传输表面。
