Ga Desorption Kinetics in the Molecular Beam Epitaxy of AlGaN Nanowires for Ultrashort Wavelength Light-Emitting Diodes
Bibliographic record
Abstract
In this work, we show that by growing AlGaN nanowires with molecular beam epitaxy (MBE) in a Ga highly desorbing regime, light-emitting diodes that can emit light at 209 nm are obtained. Detailed light emission characteristics and transmission electron microscopy studies indicate that such a light emission is due to the formation of AlN. The correlation between Ga desorption and electroluminescence (EL) is further investigated by using a unique approach with two different Al sources. It is found that the Ga desorption related to the surface-migrated Ga adatoms along the nanowire sidewall drastically affects the device EL properties, rather than the impinged Ga adatoms on the nanowire top surface. The unveiled correlation between the Ga desorption kinetics and EL properties could advance the development of technically important, ultrashort, wavelength-tunable semiconductor ultraviolet light-emitting diodes using AlGaN nanowires.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
