Gd<sub>5</sub>Si<sub>4−<i>x</i></sub>P<sub><i>x</i></sub>: Targeted Structural Changes through Increase in Valence Electron Count
Bibliographic record
Abstract
Phase transformations in the Gd(5)Si(4-x)P(x) system (0 <or= x <or= 2), studied through X-ray diffraction techniques, reveal an intimate coupling between the crystal structure and valence electron count. An increase in the valence electron count through P substitution results in breaking the interslab T-T dimers (d(T-T) = 3.74 A; T is a mixture of Si and P) and shear movement of the ( proportional, variant)(2)[Gd(5)T(4)] slabs in Gd(5)Si(2.75)P(1.25). The Gd(5)Si(2.75)P(1.25) phase extends the existence of the orthorhombic Sm(5)Ge(4)-type structures to the valence electron count larger than 31 e(-)/formula unit. Tight-binding linear-muffin-tin-orbital calculations trace the origin of the T-T dimer cleavage in Gd(5)Si(2.75)P(1.25) to a larger population of antibonding states within the dimers.

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.
