Abstract

fetched live from OpenAlex

In this work we investigate metalorganic chemical vapor deposition (MOCVD) diffusion of zinc into undoped InP and InGaAs using dimethylzinc as the diffusant source. The resulting diffusion profiles are measured using secondary ion mass spectrometry. Systematic errors introduced by multiple diffusions are explored and a simple model of reactor transients is introduced to explain the observed departures from the expected square-root behavior. Results of zinc diffusion into high-speed avalanche photodetectors are also presented to demonstrate the ability of MOCVD based diffusion to target diffusion depths with strict tolerances.

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.
