Abstract

fetched live from OpenAlex

Abstract In this work we have studied the effect of current density and UV illumination on the morphology of porous SiC formed by electrochemical etching. Raman spectroscopy was also carried out, in order to correlate the porous SiC structure with the obtained spectra. We show that current density is important in controlling the type of structure, whereas UV illumination plays a role in pore nucleation at lower current densities. The shape of the Raman spectra, in particular the longitudinal optical (LO) peak, also depends strongly on the SiC nanoscale morphology. (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

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.
