Single-Emitter Spectra from an Ensemble
Jonah R. Horowitz, Oliver J. Tye, Oliver M. Nix +5
The heterogeneity in nanoscale emitters hinders efforts to understand their basic photophysics and limits their use in practical applications. Existing methods have difficulty accu…
Oxygen vacancy formation in ZnSeTe blue quantum dot light-emitting diodes
Shaun Tan, Sujin Park, Seung-Gu Choi +9
Recent advancements have led to the development of bright and heavy metal-free blue-emitting quantum dot light-emitting diodes (QLEDs). However, consensus understanding of their di…
Morphological and Chemical Changes in Cd-free Colloidal QD-LEDs During Operation
Ruiqi Zhang, Jamie Geng, Shaun Tan +12
Heavy metal-free quantum-dot light-emitting devices (QD-LEDs) have demonstrated remarkable brightness, saturated color, and high efficiencies across a broad spectral range. However…
Predicting Organic-Inorganic Halide Perovskite Photovoltaic Performance from Optical Properties of Constituent Films through Machine Learning
Ruiqi Zhang, Brandon Motes, Shaun Tan +7
We demonstrate a machine learning (ML) approach that accurately predicts the current-voltage behavior of 3D/2D-structured (FAMA)Pb(IBr)3/OABr hybrid organic-inorganic halide perovs…
