Development of dielectric and amorphous-silicon-based thin film coatings for room- and cryogenic temperature applications
Bibliographic record
Abstract
This paper reports on the development of dielectric and amorphous silicon-based thin film stacks for applications at room and liquid nitrogen (LN) cryogenic temperatures. The deposition process was performed using assisted energetic evaporation processes such as Reactive Low Voltage Ion Plating (RLVIP) and Ion Assisted Deposition (IAD). Dielectric coatings produced by RLVIP exhibited fairly good stability at LN temperature. Indeed, as compared to room temperature, a spectral shift of ∇λ0.5 = -2.9 nm at half maximum was obtained for a 3-cavity bandpass filter centered at 1570 nm. Amorphous silicon and silicon dioxide stacks deposited by IAD processes were tested for optical applications. Amorphous silicon thin films showed good mechanical stability at LN temperature. The influence of deposition parameters and operating temperature on the electrical, mechanical and optical properties of amorphous Si films was investigated.

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.
