Enhancing Two-Dimensional Electronic Spectroscopy for Layered Halide Perovskites
The photophysics of layered halide perovskites reveals a rich disposition of exciton behavior. Two-dimensional electronic spectroscopy (2DES) is a powerful technique for investigating such excitonic interactions and dynamics. However, the wide spectral range of layered perovskites presents a challenge in studies utilizing conventional 2DES setups to simultaneously probe their interacting excitonic
