Spectroscopic signatures of biexcitons: A case study in Ruddlesden-Popper lead-halides
Katherine A. Koch, Esteban Rojas-Gatjens, Martin Gomez-Dominguez +3
Exciton-exciton interactions are fundamental to the light-emitting properties of semiconductors, influencing applications from lasers to quantum light sources. In this study, we in…
Fine-Tuning Exciton Polaron Characteristics via Lattice Engineering in 2D Hybrid Perovskites
Katherine A Koch, Martin Gomez-Dominguez, Esteban Rojas-Gatjens +4
The layered structure of 2D metal halide perovskites (MHPs) consisting of an ionic metal halide octahedral layer electronically separated by an organic cation, exhibits strong coup…
Resolving exciton and polariton multi-particle correlations in an optical microcavity in the strong coupling regime
Victoria Quirós-Cordero, Esteban Rojas-Gatjens, Martín Gómez-Dominguez +7
Multi-particle correlations of exciton-polaritons and reservoir-excitons in the strong light-matter coupling regime dictate the quantum dynamics of optical microcavities. In this l…
Unveiling multi-quantum excitonic correlations in push-pull polymer semiconductors
Yulong Zheng, Esteban Rojas-Gatjens, Myeongyeon Lee +2
Bound and unbound Frenkel-exciton pairs are essential transient precursors for a variety of photophysical and biochemical processes. In this work, we identify bound and unbound {Fr…
Exciton-photocarrier interference in mixed lead-halide-perovskite nanocrystals
Esteban Rojas-Gatjens, Quinten A. Akkerman, Liberato Manna +2
The use of semiconductor nanocrystals in scalable quantum technologies requires characterization of the exciton coherence dynamics in an \emph{ensemble} of electronically isolated…
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…
