In the table below are Seebeck coefficients at room temperature for some common, nonexotic materials, measured relative to platinum. [8] The Seebeck coefficient of platinum itself is approximately −5 μV/K at room temperature, [9] and so the values listed below should be compensated accordingly. For example, the Seebeck coefficients of Cu, Ag ...
The results of this method showed homogenous thermoelectric properties throughout the material and a thermoelectric figure of merit ZT of 0.9 for p-type samples and 0.6 for n-type samples. The Seebeck coefficient of this material was also found to increase with increasing temperature up to around 200 °C. [113]
The thermopower, or Seebeck coefficient, of a material, which governs its thermoelectric properties (a misnomer, as this quantity has units of voltage per unit temperature) The power output of a thermoelectric generator that uses the Seebeck effect; Radioisotope thermoelectric generator
The Seebeck coefficients generally vary as function of temperature and depend strongly on the composition of the conductor. For ordinary materials at room temperature, the Seebeck coefficient may range in value from −100 μV/K to +1,000 μV/K (see Seebeck coefficient article for more information).
English: Absolute Seebeck coefficients of various metals up to high temperatures, mainly from Cusack & Kendall (1958). The data for lead (Pb) is from Christian, Jan, Pearson, Templeton (1958). The data for lead (Pb) is from Christian, Jan, Pearson, Templeton (1958).
The typical efficiency of TEGs is around 5–8%, although it can be higher. Older devices used bimetallic junctions and were bulky. More recent devices use highly doped semiconductors made from bismuth telluride (Bi 2 Te 3), lead telluride (PbTe), [10] calcium manganese oxide (Ca 2 Mn 3 O 8), [11] [12] or combinations thereof, [13] depending on application temperature.
Seebeck effect, the physical effect responsible for the generation of voltage in a thermopile; Thermoelectric materials, high-performance materials that can be used to construct a compact thermopile that delivers high power
Effective masses can also be estimated using the coefficient γ of the linear term in the low-temperature electronic specific heat at constant volume . The specific heat depends on the effective mass through the density of states at the Fermi level and as such is a measure of degeneracy as well as band curvature
