Temperature-Induced Crossover of Coherent Phonon Mechanisms in Chiral 2D Perovskites
Katherine A Koch, Matthew P Hautzinger, Matthew C Beard +1
The coupling between electronic excitations and lattice degrees of freedom fundamentally dictates the optoelectronic functionality of hybrid perovskites. While the potential energy…

Biexcitons in Ruddlesden-Popper Metal Halides Probed by Nonlinear Coherent Spectroscopy
Katherine A. Koch, Carlos Silva-Acuña, Ajay Ram Srimath Kandada
Excitons and their correlated complexes underpin the rich photophysics of quantum-confined semiconductors. Among these, biexcitons -- bound states of two electrons and two holes --…
