Abstract
Abstract Crystalline–amorphous core–shell silicon nanowires (SiNWs) grown separately on glass and stainless steel substrates were investigated by Raman spectroscopy. Raman spectra confirmed the presence of crystalline and amorphous silicon phases in both samples. With respect to bulk silicon, the crystalline Raman peaks for the nanowires grown on a glass substrate showed much larger red shift and spectral broadening as compared to that of the nanowires grown on stainless steel. The Raman shift was attributed to local heating which was further confirmed by the reduction in red shift of the Raman spectrum at lower incident powers for both samples. For a low input power of 0.8 mW, the nanowires grown on stainless steel showed no shift in the first order Raman peak as compared to bulk silicon, however a small spectral broadening was still observed. magnified image TEM images for the nanowires grown on steel substrate.

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 it
