Abstract

A Standard Reference Material (SRM) for the Seebeck coefficient is critical for inter-laboratory data comparison and for instrument calibration. To develop this SRM, we have conducted an international round-robin measurement survey of two candidate materials-undoped Bi2Te3 and constantan (55% Cu and 45% Ni alloy). Measurements were performed in two rounds by twelve laboratories involved in active thermoelectric research using a number of commercial and custom-built measurement systems and techniques. We report the results of these measurements and the statistical analysis performed. Based on this extensive study, we have selected Bi2Te3 as the prototype standard material.
