Abstract

fetched live from OpenAlex

The functional properties, such as color rendering index (CRI) and correlated color temperature (CCT) of nanowire white light emitting diodes (LEDs), have been studied. The nanowire LEDs can generate broad spectrum white light, and by controlling the growth conditions, it is easy to tailor the spectrum. This is a significant advantage over phosphor converted or nanocrystal based white light sources since it is difficult to modulate the spectrum while maintaining high efficiency using these conventional methods. The authors demonstrated that the InGaN/(Al)GaN dot-in-a-wire heterostructure LEDs can generate high CRI values of 94–98 in both warm and cool white regions. Furthermore, the generated light demonstrates relatively stable CCT, CRI, and Commission Internationale d'Eclairage coordinates at different injection currents.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
