pH Regulates Ion Dynamics in Carboxylated Mixed Conductors
Zeyuan Sun, Mengting Sun, Rajiv Giridharagopal +12
Coupled ionic and electronic transport underpins processes as diverse as electrochemical energy conversion, biological signaling, and soft adaptive electronics. Yet, how chemical e…
Increased Brightness and Reduced Efficiency Droop in Perovskite Quantum Dot Light-Emitting Diodes using Carbazole-Based Phosphonic Acid Interface Modifiers
Gillian Shen, Yadong Zhang, Julisa Juarez +8
We demonstrate the use of [2-(-carbazol-9-yl)ethyl]phosphonic acid (2PACz) and [2-(3,6-di--butyl--carbazol-9-yl)ethyl]phosphonic acid (t-Bu…
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 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…
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…
