Stability and Electronic Characteristics of Epitaxial Silicene Multilayers on Ag(111)
Bibliographic record
Abstract
In this study, the stability and electronic characteristics of epitaxial silicene bilayers and multilayers on the Ag(111) surface are investigated through synchrotron‐based soft X‐ray emission and absorption spectroscopy and first‐principles, full‐potential density functional theory simulations. The calculations predict a novel tristable AA‐stacked bilayer structure that can explain the (√3 × √3)R30° honeycomb topography commonly observed through scanning tunneling microscopy and noncontact atomic force microscopy. It is reported that the electronic structure of this epitaxial bilayer is similar to those of epitaxial monolayers on Ag(111), namely, metallic and showing significant interaction with the underlying substrate. However, the soft X‐ray spectroscopy experiments suggest that during multilayer growth a majority of the epitaxial silicon reverts to a bulk‐like state, a result that has significant implications toward the existence of large‐area epitaxial silicene multilayers.

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.
