讲座人介绍：
Dr. Junho Choi is an assistant professor in the department of Physics at Kyung Hee University located in Seoul, South Korea. Dr. Choi obtained his Ph. D. in Physics at the University of Texas at Austin in 2020 and continued his 2D material research at the National High Magnetic Field Laboratory in Los Alamos National Laboratory as a Director’s postdoc fellow. And then he moved back to South Korea and started a new position as a senior research scientist in Korea Research Institute of Standards and Science until last year. His expertise is optical spectroscopy on various 2D quantum materials such as 2D semiconductors and 2D magnets and research interest is many-body physics and quantum phenomena in 2D heterostructures.
报告主题：
This lecture will provide an introductory overview of optical spectroscopy techniques and their applications in the study of two-dimensional (2D) quantum materials. As the field of 2D materials has rapidly expanded, understanding their unique optical and electronic properties has become important for advancing quantum science. We will begin with a basic review of key concepts in linear and nonlinear optical spectroscopies. Participants will gain insights into recent breakthroughs in the field, including moiré excitons and twist angle dependent tunable optical properties in twisted semiconducting bilayers. This session is designed for undergraduate students who are new to the field of 2D quantum materials and seek a comprehensive introduction to the application of optical spectroscopy in this cutting-edge area of research.
