Abstract

fetched live from OpenAlex

The authors consider strain compensation for typical multiple quantum well (MQW) laser structures using an energy balance model and determine the theoretical limitations of structural stability based on uncompensated reliability data from the literature. Strain compensation is the technique used to balance tensile and compressive forces in alternating layers to render the stack strain neutral. Strain compensation must be given careful consideration in the design and synthesis of strain neutral structures. Strain compensation holds the promise of reduced defect densities with enhanced stability and should permit very highly strained QW optoelectronic devices to be fabricated which are predicted to have considerably enhanced performance and reliability.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

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.
