Abstract
Microscale visible light emitting diodes (LEDs), as well as LEDs and laser diodes operating in the mid and deep ultraviolet (UV), have emerged as the frontier of semiconductor optoelectronics and are poised to revolutionize mobile displays, virtual/augmented reality, water purification, sterilization, and many other critical applications. In this article, we provide an overview of some recent developments of III-nitride nanostructures by molecular beam epitaxy and their applications in micro-LEDs and deep UV optoelectronics including LEDs and laser diodes. Due to the efficient surface strain relaxation, III-nitride nanostructures exhibit significantly reduced dislocation densities compared to their conventional quantum well counterparts. Studies have further shown that p-type Mg-dopant incorporation is much more efficient in nanostructures. These attributes have been exploited to realize high efficiency micro-LEDs operating in the deep visible (e.g., green and red) and to achieve relatively efficient LEDs operating in the UV-C and far UV-C spectra. The utilization of III-nitride nanostructures to realize electrically injected laser diodes with relatively low threshold is also presented.

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
