(Invited) The Thermal Budget of Hydrogen-Related Donor Profiles: Diffusion-Limited Activation and Thermal Dissociation
Bibliographic record
Abstract
The impact of the thermal budget on hydrogen-related donor profiles in high purity silicon implanted with protons in the MeV energy range is investigated. The appearance of donor profiles is limited to the annealing temperature between 350 {degree sign}C and 500 {degree sign}C. The activation of doping profiles is limited by the diffusion of implanted hydrogen from the end-of-range region throughout the radiation-induced damage. This formation process of profiles is described by a diffusion model with an effective activation energy of 1.2 eV. The hydrogen-related donors are radiation-induced defect complexes decorated by hydrogen. The thermal stability of these donors is limited by dissociation. The deactivation of the doping is modeled by two hydrogen-related donor species with effective dissociation energies of 2.5 eV and 3 eV. The described formation and dissociation mechanisms define upper and lower limits of the post-implantation thermal budget, respectively, for sensible use of proton implantation doping in crystalline Silicon.

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.
