Abstract

fetched live from OpenAlex

The conventional Cu-induced crystallization of a-Ge has been facilitated by different types of external stress mechanically applied to the flexible substrate. It has been observed that in the case of compressive stress, crystallization becomes possible at temperatures as low as 130 °C and evolves as stress becomes more stringent. High electrical conductance and a hole mobility of 110 cm2/V s show the crystallinity of the Ge film, further confirmed by x-ray diffraction, scanning electron microscopy, and transmission electron microscopy analyses. The temperature of the annealing process (between 130 and 180 °C) expedites the process (from 6 to 1 h) as it is increased, but the principal mechanism seems to be independent of temperature. Temperatures higher than 180 °C are detrimental to the plastic substrate, polyethylene terephthalate. Evolution of cracks in Ge layer has been studied as the main consequence of the interfacial stress between Ge layer and substrate. The crack density was minimized by patterning the a-Ge layer before annealing. The main explanation of the physical phenomenon accounting for crystallization is believed to be the externally applied compressive stress, which reinforces the inherently present internal stress between the layer and the substrate.

Full frame distilled prediction

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.
