Abstract

fetched live from OpenAlex

Abstract Ion implantation is applied here to prevent metallic silver (Ag) thin films from dewetting on a sapphire substrate during annealing. In these experiments, silicon (Si) and indium (In) atoms are implanted into Ag thin films grown directly on sapphire, which are then annealed for different time periods to introduce film dewetting. It is observed that trace amounts of 10 14 cm −2 dopants significantly retard the film grain growth, alter the film surface wetting features, and trivially influence the electrical and optical performance of the original film. A grain growth model with the presence of solute species is introduced here, combined with a thermodynamic simulation of film dewetting. It is found that doping ions introduce solute drag into Ag grains thereby significantly retarding the grain growth by generating a limiting grain size. The shrunken grains then alter the film surface energy distribution, transferring the most stable state from the dewetting phase to the wetting phase. The approach provides a novel strategy to suppress metallic thin films from dewetting with high stability, durability, and insignificant impact on the film performance without using an adhesion layer and also potentially expands the thermal processing window for metallic thin films.

Teacher imitation

Not 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.
