Abstract

fetched live from OpenAlex

Analysis of existing data on muonium in GaAs provides an extensive set of ionization energies and barriers for motion and site transitions. Within an accepted model of muonium behavior in III-V compounds, these results establish the energy relationships among observed muonium centers in GaAs, including the metastable states. This analysis places the (0/+) donor level at $0.17\phantom{\rule{0.3em}{0ex}}\mathrm{eV}$ below the conduction band edge and the (\ensuremath{-}/0) acceptor level at roughly $0.60\phantom{\rule{0.3em}{0ex}}\mathrm{eV}$ above the top of the valence band for this very light hydrogen isotope, thus locating the muonium equivalent of the H(+/\ensuremath{-}) pinning level about $0.21\phantom{\rule{0.3em}{0ex}}\mathrm{eV}$ above midgap in GaAs, nearly $0.5\phantom{\rule{0.3em}{0ex}}\mathrm{eV}$ higher than predicted.

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.
