Electronic structure of the Ge(111)‐5 × 5 wetting layer on Si(111)‐7 × 7
Bibliographic record
Abstract
Abstract This work reports an ab initio study of the Ge(111)‐5 × 5 reconstruction, which forms on top of a Si(111)‐7 × 7 substrate. Detailed descriptions of the structural and electronic properties of this surface, obtained from density‐functional calculations, are presented and analyzed. Many similarities with the structural and electronic–electronic properties of related structures such as Si(111)‐7 × 7 and Si(111)‐5 × 5 were found, in particular the similar localisation properties of the eigenstates around the fermi level, the non‐zero density of states at the fermi level, a larger charge density associated with the dangling bonds on the faulted half cell compared with those of the unfaulted half, and the structural relaxations of key surface atoms and bonds, although the magnitudes of these relaxations are somewhat smaller than has been calculated for Si(111)‐7 × 7. The calculated charge density distribution is interpreted in terms of population analysis to obtain information on the bonding mechanisms at the surface. (© 2007 WILEY‐VCH Verlag GmbH & Co.

How this classification was reachedexpand
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.
