Correlation between Electrical and Optical Properties of Tantalum Anodic Oxide and Electron Cyclotron Resonance Etching Studies of E-beam Deposited Ta<sub>2</sub>O<sub>5</sub> Films
Bibliographic record
Abstract
The anodicTa2O5 films were grown in 5ml/98%H2SO4 electrolyte. Discharge currents were collected immediately after growth. The optical properties were studied with a Spectroscopic Ellipsometer, over a wide range of frequencies from the UV to the IR. It was established that films for which the discharge current followed the known "~ -1" power dependence (characteristic of films that can sustain electric fields of MV/cm) have different optical properties as compared to films for which the discharge current is not represented by that function. Etching studies of the e-beam deposited Ta2O5 films, combined with reflectance measurements after each etch step, resulted in a shift in the reflectance spectrum as a function of film thickness, d. This empirical f versus d dependence (where f is the frequency corresponding to the reflectance minimum for each d) was used to calculate the energies of the 4d doublet of Ta+5 in Ta2O5.

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.
