Abstract
Cu 2 O and CuO have been grown with an aim to reduce junction electrical resistance when interfaced with N,N′-bis(1-naphthyl)-N,N′-diphenyl-1,1′ biphenyl 4,4′-diamine (NPB). Organic light-emitting diodes employing Cu/CuO anodes have equivalent driving voltages as devices made with indium tin oxide. Hole-injection barriers are calculated from current-voltage characteristics of CuO/NPB/Cu and Cu2O/NPB/Cu devices via theoretical simulation. Photoelectron spectroscopies are used to measure oxide valence band spectra, interfacial dipole formation, and band bending during in situ sequential deposition of NPB on each oxide. Calculated hole-injection barriers and those derived from photoemission results accord well, explaining the superior hole injection at the CuO-NPB 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
