Abstract
Helicon plasma sputtering of Fe/Si multilayer followed by thermal annealing in Ar atmosphere was used to fabricate β-FeSi_2 films. [Fe 0.5nm/Si 1.6nm]_ 120 multilayer was deposited on Si(100) substrate and then the samples were annealed at 900℃ for 2h or at 9001000℃ for 10s. Annealed samples were characterized by X-ray diffractometry(XRD), Rutherford backscattering spectroscopy, scanning electron microscopy and optical absorption measurement. (202)/(220) oriented β-FeSi_2 films are fabricated from the multilayer according to XRD patterns. It is found that there is a very small redistribution of Fe and Si components in the films during the thermal annealing, so that a good stoichiometry of FeSi_2 can be obtained. It is also revealed by scanning electron microscopy that multilayer technology can result in a smooth surface for β-FeSi_2 films. Optical absorption spectra demonstrate that the films have a direct band gap of 0.9eV at room temperature.

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.
