Exciton Bimolecular Annihilation Dynamics in Push-Pull Semiconductor Polymers
Yulong Zheng, Rahul Venkatesh, Esteban Rojas-Gatjens +2
Exciton-exciton annihilation is a ubiquitous nonlinear dynamical phenomenon in materials hosting Frenkel excitons, that has been employed to probe exciton diffusion processes in co…
Resolving nonlinear recombination dynamics in semiconductors via ultrafast excitation correlation spectroscopy: Photoluminescence versus photocurrent detection
Esteban Rojas-Gatjens, Kaila Yallum, Yangwei Shi +7
We explore the application of excitation correlation spectroscopy to detect nonlinear photophysical dynamics in two distinct semiconductor classes through time-integrated photolumi…
Chain Conformation and Exciton Delocalization in a Push-Pull Conjugated Polymer
Yulong Zheng, Rahul Venkatesh, Connor P. Callaway +6
Linear and nonlinear optical lineshapes reveal details of excitonic structure in semiconductor polymers. We implement absorption, photoluminescence, and transient absorption spectr…
