3. 주제: Understanding and Regulating Excited State Dynamics in Materials
4. 주관: EEWS대학원 김용훈 교수 (내선 1717)
Electronic excited states are quite common in nature and several applications, and the understanding and controlling of excited carrier dynamics is of fundamental and practical importance. Recent developments in time-dependent density functional theory (TDDFT)-molecular dynamics (MD) make it possible to explore excited carrier dynamics and its coupling with lattice dynamics on a femtosecond time scale. In this talk, I will present several recent studies on this subject, including the carrier multiplication induced non-thermal phase transition in phase change memory materials, the charge transfer dynamics in van der Waals heterostructures, the carrier induced transient defect formation and non-radiative recombination in semiconductors, and the photo-desorption of hydrogen on graphene.
