Abstract

fetched live from OpenAlex

This study reports electrical characteristics of highly crystalline Aluminum Nitride (AlN) films synthesized directly on Si (100) substrate. The X-ray diffraction revealed a fully textured oriented in the (002) for <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$1\ \mu \mathrm{m}$</tex> thick AlN films deposited by pulsed DC sputtering. The sweep frequency analysis (C-f) reveals that the capacitance is almost constant when increasing the frequency, resulting in a low density of trapped charges in the AlN/Si (100) interface. The dielectric permittivity was determined to be 10.3, accounting for the higher effective electrodes area due to the fringing field. The capacitance in voltage sweep (C-V) measurements for top electrodes with different diameters from 200 to <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$800\ \mu \mathrm{m}$</tex> determined the effective width of the electric field <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$(\delta)$</tex> to be <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$7.1\ \mu \mathrm{m}$</tex>.

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.
