Abstract

fetched live from OpenAlex

Abstract This work reports on the optoelectronic properties and device application of hydrogenated amorphous silicon carbide (a‐Si 1–x C x :H) films grown by plasma‐enhanced chemical vapour deposition (PECVD). The films with an optical bandgap ranging from about 1.8 to 2.0 eV were deposited in hydrogen diluted silane‐methane plasma by varying the radio frequency power. Several n–i–p structures with an intrinsic a‐Si 1–x C x :H layer of different optical gaps were also fabricated. The optimized devices exhibited a diode ideality factor of 1.4‐1.8, and a leakage current of 190‐470 pA/cm 2 at –5 V. The density of deep defect states in a‐Si 1–x C x :H was estimated from the transient dark current measurements and correlated with the optical bandgap and carbon content. Urbach energies for the valence band tail were also determined by analyzing the spectral response within sub‐bandgap energy range. (© 2010 WILEY‐VCH Verlag GmbH &amp; Co. KGaA, Weinheim)

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.
