이번 학기 콜로퀴움은 학교의 권고를 따라, 사회적 거리두기 단계와 연계하여 온라인 혹은 오프라인(온라인 방송 병행)으로 운영될 예정입니다.

여덟번째 강연에는 GIST 광물리학과의 이종석 교수님을 모시고 콜로퀴움을 개최하오니, 학과 구성원 여러분의 많은 참여를 부탁 드립니다.

코로나19 확산방지를 위해 다과는 제공하지 않습니다.

4. Place: Natural Science 1,  Room No. 31214


5. Abstract: Photon-based spectroscopic techniques have long been developed and served as a powerful tool in understanding electric and magnetic properties of condensed matters. Linear or nonlinear optical responses enable us to reveal static and dynamic properties related to fundamental degrees of freedom in solids, such as charge, spin, and lattice, which can have a direct or indirect coupling to the electromagnetic waves. In this presentation, I will discuss how nonlinear optical spectroscopy, in particular, the optical second harmonic generation technique is exploited to investigate not only the crystal structural symmetry but also electric and magnetic properties of condensed matters. The topics include (i) polar metal phase of oxide thin films, (ii) atomically thin multiferroic van der Waals materials, and (iii) hot carrier diffusion in semiconductors.
