Spectroscopy Laboratory for Advanced Materials

충북대학교 자연과학대학 화학과 신소재 분광학 연구실(Spectroscopy Laboratory for Advanced Materials) 홈페이지를 방문해 주셔서 감사합니다.

우리 연구실은 시간 분해 분광법(Time-Resolved Spectroscopy)을 기반으로 새로운 분광학적 분석 기법을 개발하고, 이를 활용하여 광촉매, 광전극, 태양전지 등 다양한 에너지 변환 반도체에서 일어나는 광여기 전하 캐리어의 생성, 이동, 재결합 및 계면 전하 전달 메커니즘을 연구하고 있습니다.

특히 Charge Carrier-Selective Heterodyne Transient Grating (CS-HD-TG) 등 독자적인 분광 기술을 지속적으로 개발하여 기존 방법으로는 직접 관측하기 어려웠던 반도체/전해질 계면의 전하 전달 활성화 에너지, 표면 트랩 상태, 전하 이동 및 재결합 동역학을 규명하고 있습니다. 이를 통해 에너지 변환 효율을 결정하는 근본적인 인자를 이해하고, 차세대 고효율 광에너지 소재의 설계 원리를 제시하는 것을 목표로 합니다.

또한 광전기화학적 물분해(Photoelectrochemical Water Splitting)를 위한 고효율 광전극 개발과 함께, 분광학과 전기화학을 융합한 새로운 분석 방법론을 제안하여 에너지 소재 연구 분야의 새로운 연구 패러다임을 제시하고자 노력하고 있습니다.

본 연구실에서는 새로운 분광 기술 개발과 에너지 소재 연구에 열정을 가진 학부생, 대학원생 및 연구원을 항상 환영합니다. 연구에 관심 있는 분들은 언제든지 아래의 연락처로 문의하시기 바랍니다.
