Electronic structure of p(2 × 3) Ag films on Si(100)
Bibliographic record
Abstract
The electronic structure of p(2 × 3) Ag films on Si(100) is studied by using electron energy loss spectroscopy (EELS) and scanning tunneling spectroscopy (STS). We observe three energy loss peaks with their loss energies around 1.28, 1.63, and 4.0 eV, respectively. They are assigned to the interband transition in the p(2×3) islands, the interface plasmon between Si(100) and Ag crystallites formed concomitantly with the p(2 × 3) islands, and a combination of the surface plasmon and interband transition of the Ag crystallites, respectively. STS over the p(2 × 3) surface also reveals a band gap around 1 eV in good agreement with the EELS observation of the interband transition. The present observation of the band gap suggests that the p(2 × 3) surface is semiconducting. Furthermore, we examine two models previously proposed for the p(2 × 3) surface against the present experimental observation by ab initio band structure calculations.

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.
