연구

우리 실험실에서는 광이온화 과정을 원하는 방향으로 조절하는 분석 도구 개발을 하고 있다. 현재 광전자분광학에서 가장 좋은 분해능을 갖는 PFI-ZEKE 와 MATI 분광기의 스펙트럼을 분석하는 가장 강력한 이론인 프레임 변환 다채널 양자결함 이론 (MQDT)은 가장 적은 수의 파라미터를 이용하여 광흡수 이온화 스펙트럼을 재현하지만, 이들 파라미터들이 어떻게 스펙트럼에 영향을 미치는지에 대해서는 알려주지 않는다. 이러한 문제점을 보완하기 위해 교란자가 있는 경우로 특화시켜 사용폭을 크게 넓힌 본 실험실에서 개발된 위상변이 MQDT를 분자계에 적용하고 이러한 경험을 토대로 ZEKE MATI 스펙트럼에서의 채널 상호작용을 분석해주고 이를 통해 가능한 이온화 패턴을 보여주는 지도를 제작하고 광이온화 과정을 원하는 방향으로 조절할 수 있도록 하는 실험학자를 위한 도구제작을 목표로 한다.
