Abstract

fetched live from OpenAlex

Ion beam intermixing is proving to be an attractive route to engineering the bandgap energies of quantum wells constructed from heterostructures in optoelectronic materials. Tests of the concept have been carried through to the device performance stage and full wafer processing. Two rather different examples of its capabilities: (a) differential wavelength adjustment on an array of GRINSCH-type laser diodes; and (b) cooling of laser facets through the use of bandgap adjusted cavity extensions, are presented. The need to better understand the physics underlying the technique is illustrated by results showing a pronounced dependence of bandgap shift upon implantation temperature.

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.
