Abstract
Despite of the technological importance of developing AlGaN deep UV LEDs on Si, there are only a few reports about AlGaN deep UV LEDs on Si based on AlGaN epilayers. Herein, we show vertical AlGaN deep UV LEDs on Si with polarization enhanced p-AlGaN epilayer. The devices emit at 278 nm, with uniform current injection. Compared to devices using standard p-AlGaN epilayer, the series resistance of devices with polarization enhanced p-AlGaN epilayer is reduced by a factor of 5. This work represents the first report of AlGaN deep UV LEDs on Si with polarization enhanced p-AlGaN epilayers.

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 it
