Abstract

fetched live from OpenAlex

Abstract\nSilicon carbide is a versatile material amenable to variety of applications from electrical\ninsulation to surface passivation, diffusion-barrier in optoelectronic and high-frequency devices.\nThis research presents a fundamental study of a-SiC:H films with variable stoichiometries\ndeposited using novel technique, DC saddle-field plasma-enhanced chemical-vapour deposition,\na departure from conventional RF PECVD commonly used in industry. DCSF PECVD is an\nalternative technique for low temperature large area deposition. Stoichiometric a-SiC:H obtained\nby fine-tuning precursor gas mixture. Annealing up to 800oC showed no significant change in\nelemental composition; particularly indicating thermal stability at stoichiometry. Ellipsometry\nshowed wide range of optical gaps whose maximum surpasses values reported in literature.\nRefractive index measured and change in values studied as function of increasing carbon content\nin the films. Also attainment of very smooth surface morphology for stoichiometric a-SiC:H\nfilms reported. Surface roughness of 1 nm rms demonstrated for films grown at temperature as\nlow as 225oC.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
