Stress-assisted nickel-induced crystallization of silicon on glass
Bibliographic record
Abstract
The effect of external mechanical stress on the crystallization of amorphous silicon deposited on thin, flexible glass substrates has been studied. A thin, 5–10 Å, layer of nickel deposited on the surface of the amorphous silicon layer acted as the seed of crystallization and the crystallization was observed to initiate at the top surface and proceed down towards the glass substrate. Application of a tensile stress during the annealing stage led to a uniform, partial crystallization of the amorphous silicon for annealing temperatures as low as 310 °C. In contrast, the application of compressive stress led to buckling of the silicon films during annealing under mechanical stress and crystallization was nonuniform over the surface of the sample. The crystalline quality of the films was investigated using scanning electron microscopy, x-ray diffraction, and transmission electron microscopy analyses. In addition, lateral polycrystalline growth of the silicon was observed for the case in which the nickel seed layer was less than 5 Å thick.

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.
