Electronic structures + Control ➡ Exploring exotic phenomena

전자 구조  + 제어 ➡ 희귀 현상 탐구

We are interested in examining exotic phenomena such as superconductivity, emergent magnetism, and metal-to-insulator transitions using (1) thin-film growth techniques and (2) angle-resolved photoemission spectroscopy (ARPES). These exotic phenomena can be controlled through thin-film growth methods, allowing us to understand the principles governing their control by investigating electronic structures.

우리 연구실의 목표는 전자 구조를 제어하여 초전도, 자성 발현, 금속-비금속 전이 등 여러가지 발현 현상을 탐구하고 이해하는 것입니다. 이를 위하여 (1) 박막 성장 방법(2) 각분해능 광전자 분광 장치를 활용하여 물질의 전자 구조를 제어하고 측정합니다.

Thin-film growth techniques

Over the past few decades, thin-film growth techniques have significantly advanced, enabling the manipulation of exotic phenomena. These thin-film growth methods provide us with effective platforms for controlling emergent phenomena.

Angle-resolved photoemission spectroscopy (ARPES)

Understanding electron correlations is vital to examining exotic phenomena. Angle-resolved photoemission spectroscopy (ARPES) is one of the most suitable experimental methods for studying electron correlations by observing the electronic structures of materials directly.
