Nanotwinning in Silicon Nanocrystals Produced by Ion Implantation
Bibliographic record
Abstract
Si nanocrystals (Si nc) were formed by the implantation of Si + into a SiO 2 film on (100) Si, followed by high-temperature annealing. The microstructure of the Si nc produced by a high-dose (3 × 10 17 cm -2 ) implantation has been extensively investigated using high-resolution transmission electron microscopy (HRTEM). For most of the Si nc (∼90%) with diameters larger than 6 nm, their configurations are characterized by the existence of nanotwins. The twinning structures include single twins, double twins, and multiple twins. The other planar defects such as stacking faults are also observed in some nanoparticles. However, in the Si nc smaller than 5 nm, no evident microstructural defects are observed. Possible reasons that no evident microstructural defects are found in the smaller Si nc are discussed. The microstructural defects inside the Si nc have a great influence on the optical properties.
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 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.
