Abstract

fetched live from OpenAlex

Abstract Porous silicon superlattices with constituent layer porosities of ∼30% and ∼60% and modulation wavelengths of 17 nm, 20 nm and 34 nm were fabricated by electrochemical etching in HF‐based electrolytes. The elastic constants of the superlattices were estimated using Brillouin light scattering spectroscopy and compared to those calculated from an effective elastic constants model (M. Grimsditch and F. Nizzoli, Phys. Rev. B 33 , 5891 (1986) [1]). The fair agreement between the experimental and calculated constants suggests that the model holds promise for predicting the elastic properties of these and possibly other porous multilayered systems.

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.
