Abstract

fetched live from OpenAlex

We have carefully investigated a number of more than 120 selected chips fabricated on one wafer, by I-V measurements at two different precisely controlled temperatures and precision CV measurements at room temperature. From these measurements the net-doping concentration, the C-V (flat-band) barrier ΦCV, the ideality n, the apparent Richardson constant Aapp and the apparent I-V barrier Φapp have been extracted for each chip. An extremely unique C-V barrier was determined showing a relative standard deviation (sigma over mean) of only 0.086%. Moreover, the average ideality n was found to be as low as 1.028 exhibiting a relative standard deviation of only 0.35%. A clear linear correlation (ρ2 = 0.968) between ideality n and apparent I-V barrier was observed. The effective Richardson constant A** of 4H-SiC in 〈0001〉 directions could therefore be extracted to be most likely in the interval 70 Acm-2K-2 < A** < 80 Acm-2K-2.

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.
