Abstract

fetched live from OpenAlex

ZnO, in its wurtzite structure, is a widely studied metal oxide due to its unique optical and electronic properties, including efficient excitonic emission at room temperature. Zinc oxide thin films were synthesized through the dehydration of various precursors. In ethanol and mono-ethanolamine, zinc acetate (I) and zinc nitrate (II) were dissolved. Glass substrates were coated using the sol-gel spin coating method (3000 rpm for 10 s), followed by heating at 250 °C. This process was done five times to make the films thicker (and allow them to form five layers on the substrate), and then they were annealed at 450 °C for 3 hours in air, yielding 200 nm-thick films. Where acetate-derived ZnO demonstrated superior performance: 92% optical transmission at 1100 nm (vs. 80% for nitrate), a widened bandgap (3.3 eV), and enlarged crystallite size (74 nm), attributed to reduced defect density and homogeneous morphology. The presence of various vibration modes in the prepared samples was also revealed by Raman spectroscopy (RS) of the annealed films. The presence of concentrated stresses within the coated films is also determined using RS, and the scanning electron microscopy results confirm the Raman E2 peaks by FE-SEM images.

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.
