Abstract
We report on the demonstration of InGaN photonic nanocrystal light emitting diodes (LEDs), which operate in the green wavelength (∼548 nm). The devices are designed to operate at the Γ point of the photonic band structure and exhibit a spectral linewidth ∼4 nm, which is nearly five to ten times narrower than that of conventional InGaN quantum well LEDs in this wavelength range. Significantly, the device performance, in terms of the emission peak and spectral linewidth, is nearly invariant with injection current, suggesting the insusceptibility to quantum-confined Stark effect commonly seen in InGaN quantum wells. The external quantum efficiency is characterized by a sharp rise with increasing current and reaches a maximum at ∼5 A/cm2, which is comparable to conventional blue quantum well LEDs. A relatively small (∼30%) efficiency droop was measured at an injection current density over 200 A/cm2 at room temperature without any active cooling.

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
