Thermoelectric properties and stability of Ba3Cu16 − <i>x</i>Se11 − <i>y</i>Te<i>y</i>
Bibliographic record
Abstract
Ba3Cu16 − xSe11 − yTey materials were synthesized with different compositions by a melting and slow cooling process. Measurement of the thermoelectric properties revealed changes during repeated measurements of the same samples. This scenario is different from the case of the isostructural sulfide variants, where the physical properties were consistently reproducible under the measurement conditions applied. Further investigations including single crystal studies after the measurements proved that this is a consequence of different Cu ion conductivity in selenides and sulfides. The reproducibility of the data was investigated by varying the maximum temperature as well as the current density. The stability of these selenides was highly dependent on the temperature; decreasing the highest measurement temperature led to full reproducibility. Finally, while the selenides exhibited larger electrical conductivity than the sulfides, their figure-of-merit zT only reached a maximum value of 0.49, compared to 0.88 of the sulfides, mostly caused by the smaller Seebeck values of the selenides.

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.
