Electrical conduction of silicon oxide containing silicon quantum dots
Bibliographic record
Abstract
Current–voltage measurements have been made at room temperature on a Si-rich silicon oxide film deposited via electron-cyclotron resonance plasma enhanced chemical vapour deposition (ECR-PECVD) and annealed at 750–1000 °C. The thickness of the oxide between Si quantum dots embedded in the film increases with increasing annealing temperature. This leads to a decreasing current density as the annealing temperature is increased. Assuming the Fowler–Nordheim tunnelling mechanism in large electric fields, we obtain an effective barrier height ϕ eff of ∼0.7 ± 0.1 eV for an electron tunnelling through an oxide layer between Si quantum dots. The Frenkel–Poole effect can also be used to adequately explain the electrical conduction of the film under the influence of large electric fields. We suggest that at room temperature Si quantum dots can be regarded as traps that capture and emit electrons by means of tunnelling.

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.
