Broad-spectrum light emission at microscopic breakdown sites in metal-insulator-silicon tunnel diodes
Bibliographic record
Abstract
In addition to Si band-edge electroluminescence (EL) near 1.1 eV, we observe hot-electron EL in metal-insulator-silicon tunnel diodes that can span a detector-limited range from 0.7 to 2.6 eV (1780–480 nm). The maximum photon energy increases with increasing forward bias. In one implementation, sub-micron-sized EL sites appear during the forward-bias stress. The number of sites grows linearly with the current, consistent with the dielectric breakdown of the insulator. We compare the poststress current-voltage data with the quantum-point-contact model. Results are presented for various p-type Si(100) devices having 2–8-nm-thick SiO2, Al2O3, and HfOxNy insulators. We also describe devices in which electron-beam lithography of an 18-nm-thick SiO2 is used to define EL sites.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
