Youngji KimVanderbilt University, Nashville, Tennessee, USA _______________________________________ Ultrafast carrier dynamics in 2D materials play a crucial role in controlling light-matter interactions at the nanoscale, enabling high-speed optoelectronic and photonic applications. By actively manipulating carrier relaxation and plasmon-phonon coupling, novel functionalities such as transient polariton modes and ultrafast optical switching can be achieved. In this work,…
