Dynamics and Reactivity of Positively Charged Muonium in Heavily Doped Si:B and Comparisons with Hydrogen
Bibliographic record
Abstract
The detailed dynamics of the positively charged muonium (${\mathrm{Mu}}^{+}$) in heavily doped $p$-type Si:B is reported. Below 200 K, ${\mathrm{Mu}}^{+}$ is static and isolated, and is located in a stretched Si-Si bond. Above $\ensuremath{\approx}200\text{ }\text{ }\mathrm{K}$, ${\mathrm{Mu}}^{+}$ diffuses incoherently. At temperatures higher than 300 K, the ${\mathrm{Mu}}^{+}\mathrm{\text{\ensuremath{-}}}{\mathrm{B}}^{\ensuremath{-}}$ complex is formed while above 520 K, it starts to dissociate. There is significant enhancement of the diffusion of ${\mathrm{Mu}}^{+}$ in Si compared to ${\mathrm{H}}^{+}$ and ${\mathrm{D}}^{+}$---this is attributed to its smaller mass.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
