Abstract

fetched live from OpenAlex

Ba 3 Cu 14 - δ Te 12 was prepared by directly reacting the elements in stoichiometric ratios at 800 °C for 3 days, followed by slow cooling. Ba 3 Cu 14 - δ Te 12 forms a new structure type, space group P 2 1 / m, with lattice dimensions of a = 11.909(2) Å, b = 21.174(4) Å, c = 11.983(2) Å, β = 117.071(4)°, and V = 2690.6(8) Å 3, for δ = 0.35(2) ( Z = 4). The structure contains corner-, edge-, and face-sharing CuTe 4 tetrahedra interconnected with almost planar CuTe 3 units. These connections result in a three-dimensional Cu atom network with numerous Cu−Cu bonds. With two Te 2 2 - dumbbells per formula unit, Ba 3 Cu 14 - δ Te 12 is an electron-precise compound when δ = 0, according to (Ba 2+ ) 3 (Cu + ) 14 (Te 2 2 - ) 2 (Te 2 - ) 8 . For δ > 0, the materials are degenerate semiconductors with moderate Seebeck coefficients and electrical conductivities, in accord with the electronic structure calculations, and exhibit extremely low thermal conductivity.

Full frame distilled prediction

Teacher imitation

Not 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.
