Low-temperature stress-assisted germanium-induced crystallization of silicon–germanium alloys on flexible polyethylene terephtalate substrates
Bibliographic record
Abstract
The application of mechanical-compressive stress during low-temperature annealing has been investigated for the crystallization of SiGe alloys on plastic substrates. It was observed that crystallization of an amorphous Ge/Cu/Ge “sandwich” can occur at temperatures as low as 130 °C with the application of an equivalent compressive strain of 0.05%. By using this sandwich as a seed for crystallization of an underlying amorphous SiGe film, partial crystallization of the film was observed to occur at a temperature of 180 °C, again under an equivalent compressive strain of 0.05%. Without the application of the compressive strain, crystallization was not observed for either system at the temperatures investigated. The atomic percentage of Si in the SiGe alloy was 35% as confirmed by Rutherford backscattering spectroscopy and the partial crystallization of the SiGe layer was verified by scanning electron microscopy, x-ray diffraction, and transmission-electron microscopy analyses.

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.
