Abstract
Relentless miniaturization has driven progress in semiconductor technology, but now, at the atomic scale, predictive descriptions of heterointerfaces (and even basic data on them) are still conspicuously absent. The authors combine atom-probe tomography with advanced modeling to study the roughness of real interfaces, and their influence on charge-carrier scattering in two-dimensional quantum confined systems. This yields a state-of-the art platform to simulate the optical gain in $e.g.$ a Si-Ge quantum cascade laser, allowing precise control of optoelectronic performance by elucidating key physical properties of heterointerfaces and their impact on device physics.

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
