<i>Ab initio</i> study of indium clusters on the Ge(5 × 5) wetting layer of Si(111)‐7 × 7
Bibliographic record
Abstract
Abstract An ab initio study of In adsorbed on the Ge(111)‐5 × 5 wetting layer, which forms on top of a Si(111)‐7 × 7 substrate, is reported. A recent experiment showed that small In clusters form on this surface with some regularity but their exact size and structure are still unknown. Results are presented of a detailed investigation of the structural and electronic properties of a single adsorbed In atom and small candidate In clusters, carried out using density‐functional calculations. Using density difference plots and population analysis, the mechanisms of bonding for different In structures are explained. Comparison of total energies shows that for a single In atom the faulted half cell is marginally preferred to the unfaulted half, and little tendency for clustering of In is found for low coverages. Both of these conclusions seem to be at odds with the experimental results and possible explanations are discussed. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

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.
