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…
Landau-Levich Scaling for Optimization of Quantum Dot Layer Morphology and Thickness for Enhanced Quantum-Dot Light-Emitting Diode Performance
Yiman Xu, Grant J. Dixon, Qing Xie +4
Quantum dot (QD) light-emitting diodes (QLEDs) are promising candidates for next-generation displays because of their high efficiency, brightness, broad color gamut, and solution-p…
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…
