Abstract

fetched live from OpenAlex

In this study we investigate the degree to which the design methods of solid-state band-diagrams might be extended and applied to realize high performance electrochemical luminescence (ECL) heterostructures. Taking quantum dots (QDs) as a model system, we first build up a description of their ECL properties in the single-particle picture utilizing the Gerischer-Hopfield framework of electron transfer. This is then applied to the construction of single- and two-probe electrode designs, where it is shown that the internal quantum efficiencies of individual QDs can theoretically reach performance metrics competitive with solid-state devices. These near-ballistic designs}, characterized by single step carrier transfer events at each electrode, are demonstrated to only attain such high efficiencies through the use of band gap (heterostructure) engineering in the electrodes. Subsequently, we propose a further diffusive operating design composed of an electrolyte infused network of QDs, forming a functional material whereby carriers hop between QD sites. The operation of this diffusive ECL heterostructure is further analyzed to possess maximum theoretical light emission intensities and efficiencies rivalling solid-state devices. Ultimately, this work underscores the potential utility of applying band diagram based design methods and electrochemical approaches when seeking to enhance the efficiency of QD emitters for a wide range of processable electronics applications.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
