Abstract

fetched live from OpenAlex

Under appropriate conditions, the growth of InGaAs/InP on patterned InP substrates leads to the development of atomically smooth triangular structures with [111]B sidewalls and embedded in InGaAs quantum wells. Using finite element methods, we examine how the stress distribution arising from embedded compressive and tensile quantum well influences the subsequent growth of self-assembled InAs quantum dots on the sidewalls. By calculating the total strain energy of the structure we show that the InAs dots would locate preferentially along the sidewall near the location of a comprehensive quantum well and away from a tensile quantum well. We also show that the size distribution can be narrowed in a three-layer structure that consists of one compressive quantum well sandwiched between two tensile quantum wells.

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.

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.
