Abstract

fetched live from OpenAlex

We have used transmission electron microscopy and low temperature photoluminescence to study the growth by chemical beam epitaxy of self-assembled InAs/InP quantum dots as a function of growth interruption time. As the deposited InAs layer is given time to migrate on the semiconductor surface a number of different features appear. The InAs layer first forms a rough quantum well with monolayer fluctuations in width before forming elongated InAs islands. These islands are elongated along the [01-1] direction due to surface diffusion dynamics. These then break up into individual quantum dots, and slowly increase in height. These dots are found to be approximately square with their sides aligned along the 〈100〉 directions and lateral dimensions of 30–40 nm.

Full frame distilled prediction

Teacher imitation

Not 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.
