Abstract
We have studied the epitaxy, energy bandgap, and structural and optical properties of GaSbN nanostructures in the dilute antimony (Sb) limit (Sb concentration < 1%). GaSbN nanowire structures are grown on a Si substrate by plasma-assisted molecular beam epitaxy. It is observed, both theoretically and experimentally, that the incorporation of a very small amount of Sb (<1%) in GaN can substantially reduce the energy bandgap of GaN from 3.4 eV to ∼2 eV. We have further demonstrated that emission wavelengths of GaSbN nanowires can be tuned from ∼365 nm to 600 nm at room-temperature by varying the Sb incorporation. Functional GaSbN nanowire light-emitting diodes are also demonstrated, which exhibit strong emission in the deep-visible spectral range.

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
