Abstract
The band-gap energy of InGaNAs decreases with N content at a smaller rate than that of GaNAs. Precise absorption measurements in strained InGaNAs/GaAs quantum wells on GaAs(001) are reported, and the result is explained in the frame of the repulsion between the nitrogen level and the \ensuremath{\Gamma} conduction band. As the energy separation between both levels is larger when the In content increases, the effect of introducing nitrogen is significantly reduced. In order to get a quantitative description of experimental results, the model includes a detailed description of the local N environment. Results suggest that in our InGaNAs/GaAs quantum wells grown by molecular beam epitaxy, the N configuration should be close to the statistical one. Using this model to explain the effect of annealing on band structure, we conclude that, on average, N atoms gain one additional nearest-neighbor In atom during the annealing, leading to a moderately large band-gap blueshift of 20--30 meV.

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
