Abstract

fetched live from OpenAlex

Metamorphic buffer layers offer a wide variety of lattice constants for substrate on which devices can be grown. However, almost in all cases, the surface of the pseudo-substrate contains striations which are known as “cross-hatch.” Although, it is accepted that this surface undulation is related with the underlying gridlike misfit dislocations (MDs), the exact correlation is still to be determined. In this article, degree of polarization of photoluminescence maps and atomic force microscopy were used to analyze the correlation between surface undulation and the underlying strain field of the pseudo-substrate. From the correlation, it can be said that the surface undulation is not formed after MD nucleation, but MDs form in some of the troughs of the undulation.

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.
