Blistering of GaAs by low keV H, D, and He ions
Bibliographic record
Abstract
The thermally activated blistering of the GaAs (100) surface after 5- and 10keV H, D, and He ion implantations was investigated. A large isotope effect is observed as the critical blistering fluences are two to three times higher for D than for H ions. Blistering and exfoliation are also obtained for very low He ion fluence, contrary to Si which is impervious to He blistering in the same conditions. The exfoliated crater depth depends strongly on the He fluence, varying, at 10keV, from 75±10nm (for 1.6×1016He∕cm2), consistent with the ion projected range determined by computation, to a saturation value of 155±10nm for doses >4×1016He∕cm2. Our results suggest that the fracture leading to cleavage is triggered at a local He concentration of about 2at.%, where dislocations and nanocavities are created.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
