Abstract
The crystallography of epitaxial dysprosium silicide nanometer scale islands on Si(001) has been studied using transmission electron microscopy. Cross-sectional high resolution images show that the silicide nanostructures have either hexagonal or orthorhombic/tetragonal crystal structure. Moir\'e fringe patterns from plan view specimens show that elongated islands have the hexagonal structure while islands with smaller aspect ratios have the orthorhombic/tetragonal structure of $\mathrm{Dy}{\mathrm{Si}}_{2}$. Less lattice distortion and/or fewer dislocations are seen along the small lattice mismatch direction for both the hexagonal and orthorhombic/tetragonal silicides, indicating that lattice mismatch plays an important role in controlling island morphology.

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
