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…
A closed-loop AI framework for hypothesis-driven and interpretable materials design
Kangyu Ji, Tianran Liu, Fang Sheng +3
Scientific hypothesis generation is central to materials discovery, yet current approaches often emphasize either conceptual (idea-to-data) reasoning or data-driven (data-to-idea)…
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…
Disentangling the Effects of Simultaneous Environmental Variables on Perovskite Synthesis and Device Performance via Interpretable Machine Learning
Tianran Liu, Nicky Evans, Kangyu Ji +12
Despite the rapid rise in perovskite solar cell efficiency, poor reproducibility remains a major barrier to commercialization. Film crystallization and device performance are highl…
Overcoming the surface paradox: Buried perovskite quantum dots in wide-bandgap perovskite thin films
Hao Zhang, Altaf Pasha, Isaac Metcalf +25
Colloidal perovskite quantum dots (PQDs) are an exciting platform for on-demand quantum, and classical optoelectronic and photonic devices. However, their potential success is limi…
