Traceable measurements of electrical conductivity and Seebeck coefficient of β-Fe0.95Co0.05Si2 and Ge in the temperature range from 300 K to 850 K

The paper describes a measuring system and a measuring method to measure the Seebeck coefficient and the electrical conductivity of different bulk materials. Some improvements of the original setup allow a reduction of the achievable relative measurement uncertainty regarding the Seebeck coefficient to a few percent. This is demonstrated by the results of Seebeck coefficient measurements of metallic and different semiconducting samples.
