Abstract
We have studied the electronic structure of (Ga 1– x Zn x )(N 1– x O x ) as a function of zinc and oxygen concentration ( x ) using soft X-ray emission (XES) and absorption (XAS) spectroscopy. We have constructed a binding energy model of the compound’s valence band using common metal features found in both N K and O K XES spectra. By comparing the spectra with theoretical DFT models, we determine that our measurements describe an inverted gap heterostructure of GaN and ZnO with two optical gaps characteristic of each phase, 2.6 and 2.8 eV, respectively. We observe a band gap reduction of 0.4 eV across the range of x tested, which is attributed to repulsion between each phase’s conduction band onset due to the proximity of states at the phase interface.

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
