Abstract

fetched live from OpenAlex

Dilute nitride semiconductors of composition GaAs1−xNx (0.0017<x<0.0115) are grown by plasma-assisted molecular beam epitaxy with a helical resonator plasma source for active nitrogen. The plasma source is self-starting at the operating pressure and can be operated at two different frequencies for which the emission spectrum is dominated by N2 molecules or by N atoms. For the same power the molecular-rich mode is found to produce a higher flux of active nitrogen. After extended operation the plasma tube becomes contaminated with As which reduces the flux of active nitrogen and creates a below band gap emission band in the photoluminescence of the GaAs1−xNx. For the clean discharge tube no difference is observed in the photoluminescence for samples grown in the molecule-rich or atom-rich mode.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
