Abstract

fetched live from OpenAlex

Abstract A thorough study on the thermoelectric potential of the layered compound SnBi 2 Te 4 is presented. Phase range studies on SnBi 2 Te 4 , unit cell parameters by powder X‐ray diffraction, and electronic structure calculations (both LDA and GGA functional) were performed. Physical property measurements regarding substitution of tin and bismuth with the triel ( Tr = Ga, In, Tl) elements are presented towards the improvement of thermoelectric properties, according to Tr x Sn 1– x Bi 2 Te 4 and Tr x SnBi 2– x Te 4 . The range of inclusion was generally over 0.01 ≤ x ≤ 0.15 to monitor compound changes as well as phase purity limits. Seebeck coefficient, S , electrical conductivity, σ , and thermal conductivity, κ , were measured, yielding the dimensionless Figure of merit, ZT , data over a temperature range between 300 K and 680 K. Results of partial replacements of tin and bismuth are compared and reported. ZT max values range from 0.10 to 0.34 depending on the dopant, achieved at temperatures from 355 K to 420 K.

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.
