Abstract
We have successfully developed a Seebeck coefficient Standard Reference Material (SRM), Bi2Te3, that is essential for interlaboratory data comparison and for instrument calibration. Certification measurements were performed using a differential steady-state (DC) technique on 10 samples (15 measurements)randomly selected from a batch of 390 bars. The certified Seebeck coefficient values are provided from 10 K to 390 K and they are further supported by transient (AC) measurements. The availability of this SRM will validate measurement results, leading to a better understanding of structure/property relationships and the underlying physics of potential high efficiency thermoelectric materials.Citation
