Role of Nonequivalent Atomic Step Edges in the Growth of InGaN by Plasma-Assisted Molecular Beam Epitaxy
Bibliographic record
Abstract
In this work, we study the growth mechanisms of InGaN in plasma-assisted molecular beam epitaxy (PAMBE). We demonstrate that for a metal-rich regime, in the range in which growth temperature limits the maximum In content, growth rate depends on gallium flux. This mechanism was investigated by the growth of InGaN/InGaN multi quantum wells (MQWs). We show that for constant growth temperature and nitrogen flux, the growth rate of MQWs decreases with decreasing gallium flux. We demonstrate also that at constant growth temperature and gallium flux, the In content in InGaN layers depends on nitrogen flux. We present an InGaN growth model that describes indium incorporation as a function of gallium and nitrogen fluxes, assuming that nonequivalent atomic step edges play an important role in indium incorporation mechanisms in PAMBE.

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.
