Abstract

fetched live from OpenAlex

We present a novel p-gallium nitride (GaN) gate HEMT structure with reduced hole concentration near the Schottky interface by doping engineering in metal-organic chemical vapor deposition (MOCVD), which aims at lowering the electric field across the gate. By employing the additional unintentionally doped GaN (u-GaN) layer, the gate leakage current is suppressed and the gate breakdown voltage is boosted from 10.6 to 14.6 V with negligible influence on the threshold voltage and ON-resistance. A reduced Mg concentration in the u-GaN layer was confirmed by secondary-ion mass spectrometry. Time-dependent gate breakdown measurements reveal that the maximum gate drive voltage increases from 6.2 to 10.6 V for a ten-year lifetime with a 1% gate failure rate, which effectively expands the operating voltage margin of the p-GaN gate HEMTs without any other additional process step.

Full frame distilled prediction

Teacher imitation

Not 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.
