Abstract

fetched live from OpenAlex

Low-energy (∼0.5 MeV) electrons arising from (60)Co γ-irradiation were used to create phosphorus-vacancy (PV) pairs and oxygen-vacancy pairs in Czochralski-grown Si. Positron annihilation data show that PV pairs anneal in two stages: the commonly observed stage around 125 °C, where one third of the pairs disappear with an activation energy of 0.8 ± 0.2 eV, and a new stage where none disappear, but form PV-oxygen complexes with an activation energy of 2.0 ± 0.2 eV.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
