Abstract
The temperature dependence of the width $\ensuremath{\Gamma}$ of the zero-phonon emission line in self-assembled $\mathrm{In}\mathrm{As}∕\mathrm{Ga}\mathrm{As}$ quantum dots has been studied for $T<50\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. In single dot experiments on laterally patterned samples we find a linear increase of $\ensuremath{\Gamma}$ with $T$, with a slope that systematically increases with decreasing size of the mesa structure. This result is to be contrasted with the absence of such a dependence in four-wave mixing on unpatterned samples. The features are shown to be consistent with a theory in which the excitons interact with phonons whose linewidths are given by scattering at surfaces due to patterning.

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
