Isolated and assembled silver aggregates on the Si(001) surface: the initial stage of film formation
Bibliographic record
Abstract
We examined the dynamics of adsorption and the subsequent growth of submonolayered silver on Si(001) from 100 K to 230 K, using scanning tunneling microscopy and density functional theory. The dynamics is demonstrated to depend on substrate temperature, as described in the following three stages: (I) at 100-140 K, silver is adsorbed as isolated aggregates (regular-Ag4, variant-Ag4 and Ag2), in the absence of single silver adatoms. The spontaneous formation of silver aggregates arises from the hot-atom motion upon the initial impingement of individual silver atoms onto the Si(001) substrate. (II) At 140-190 K, the migration of isolated Ag-aggregates is sufficiently activated, leading to the formation of Ag-chains by surface polymerization. (III) At 190-230 K, there is implication that the Ag-chains become mobile on Si(001), en route to forming patches of 2×2 Ag-films by agglomeration.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
