Abstract

fetched live from OpenAlex

Hot electrons are generated from the decay of LSPR modes.Surface-enhanced Raman spectroscopy is used to monitor hot electron generation using a dehalogenation reaction.In this thesis, Ag, Au, and AuAg nanoparticle substrates were produced and coated with halogenated thiophenols.The dipole and coupled LSPR modes associated with the nanoparticle substrate both generate hot electrons under illumination.The hot electron yield was determined for each LSPR modes.It was found that the dipole LSPR mode produced a larger yield of hot electrons than the coupled LSPR mode.The enhanced hot electron yield for the dipole mode was reported for both Ag-slides and AuAg-slides; additionally, the same result was obtained for both halogenated thiophenols.This work shows that the dipole LSPR mode is more suitable for the generation of hot electron than the coupled mode.Additional work is required to make the coupled LSPR mode an efficient hot electron generator.

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.
