Pulsed-plasma deposition of amorphous diamond-like carbon films on copper
Bibliographic record
Abstract
Summary form only given. Using the new pulsed-plasma source ion implantation (PSII) as an alternate implantation technique for diamond growth by the carbon-implantation-out-diffusion (CIOD) method allows us to investigate the effect of a higher C ion flux, which is suspected to be the main factor leading to diamond formation in copper. Single crystal and polycrystalline copper disk samples were dc-biased at negative voltages ranging from 0-30 V and exposed to a pulsed or dc methane (pure or 1% CH/sub 4/ in H/sub 2/) plasma. The copper substrate temperature is kept at either 800-1000/spl deg/C or at ambient temperature during plasma exposure. The resulting films are examined by Raman spectroscopy, XPS, and SEM. Preliminary results show only growth of graphitic and diamondlike carbon films on copper substrates negatively dc-biased at 0-10 kV and kept at 800-950/spl deg/C during exposure to 1% CH/sub 4//H/sub 2/ dc plasma.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
