Abstract

fetched live from OpenAlex

We report direct detection of the formation and subsequent breakup of a complex containing positively charged muonium ( ${\mathrm{Mu}}^{+}$) and a substitutional ${\mathrm{Zn}}_{\mathrm{Ga}}$ acceptor in heavily doped $p$-type GaAs:Zn. ${\mathrm{Mu}}^{+}$ diffuses above 200 K with a hop rate $\ensuremath{\nu}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}{\ensuremath{\nu}}_{0}{e}^{{\ensuremath{-}E}_{\ensuremath{\nu}}{/k}_{B}T}$ where ${\ensuremath{\nu}}_{0}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}(7.7\ifmmode\pm\else\textpm\fi{}2.0)\ifmmode\times\else\texttimes\fi{}{10}^{8}{\mathrm{s}}^{\ensuremath{-}1}$ and ${E}_{\ensuremath{\nu}}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.15(4)\mathrm{eV}$. Above 350 K, it forms the complex with a trapping radius of $500\ifmmode\pm\else\textpm\fi{}200\AA{}$. The Mu-Zn complex breaks up above 550 K with a dissociation energy of 0.88(7) eV and prefactor of $(5\ifmmode\pm\else\textpm\fi{}4)\ifmmode\times\else\texttimes\fi{}{10}^{12}{\mathrm{s}}^{\ensuremath{-}1}$. Above 750 K, the cyclic reaction ${\mathrm{Mu}}^{+}\ensuremath{\leftrightarrow}{\mathrm{Mu}}^{0}$ takes place.

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.
