1D and 2D Photophysics
We investigate unique physical properties of low-dimensional materials such as carbon nanotubes and two-dimensional semiconductors. Our research focuses on understanding exciton-phonon interactions, exciton dynamics, and interlayer coupling effects. We explore novel optical phenomena including upconversion luminescence and laser cooling through selective excitation of bright excitons in carbon nanotubes. We also study efficient energy transfer in two-dimensional heterostructures and photocarrier relaxation processes. Our goal is to translate these fundamental insights into applications for next-generation optical devices and quantum technologies.
