absolute seebeck coefficient meaning
The quotient, as an integral from absolute zero to the given temperature, of the Thomson coefficient of a material divided by its absolute temperature.
- Absolute Seebeck coefficients of various metals up to high temperatures, mainly from Cusack & Kendall ( 1958 ).
- Absolute Seebeck coefficient of lead at low temperature, according to Christian, Jan, Pearson, Templeton ( 1958 ).
- Determination of the absolute Seebeck coefficient therefore requires more complicated techniques and is more difficult, however such measurements have been performed on standard materials.
- Although only relative Seebeck coefficients are important for externally measured voltages, the absolute Seebeck coefficient can be important for other effects where voltage is measured indirectly.
- A publication in 1958 used this technique to measure the absolute Seebeck coefficient of lead between 7 . 2 K and 18 K, thereby filling in an important gap in the previous 1932 experiment mentioned above.
