Using a Vapor‐Phase Surfactant to Control Gold Metal Plate Growth
Bibliographic record
Abstract
Hexamethyldisilazide‐1,3‐diisopropylimidazolidine‐2‐ylidenegold(I) (1) is used to deposit gold microplates with (111) faces. In the absence of any secondary vapor‐phase surfactant, these plates show secondary nucleation and growth of gold metal nanoparticles on the (111) faces. When tetrahydrothiophene (THT) is used as a secondary, vapor‐phase surfactant, plate size increases, and secondary nucleation is controllable by temperature. Deposition of gold microplates at 370 °C using a 45 mTorr overpressure of THT shows the best experimental results, growing 20 µm2 plateaus with no apparent secondary nucleation. Computational modelling demonstrates that THT is a stronger surfactant than the carbene ligand (from the gold precursor) due to steric hindrance from the alkyl groups present in the carbene ligand.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
