What is thermopower?
The thermopower, thermoelectric power, or Seebeck coefficient of a material describes how it functions thermoelectrically.
The Seebeck coefficients, represented as S, are non-linear, and depend on the conductors' absolute temperature, material, and molecular structure.
The Seebeck Coefficients refer to the measure of the magnitude of the thermoelectric effect, which is the production of an electric potential difference when two dissimilar metals are brought into contact.
Seebeck Coefficients are significant because they allow us to measure and understand the thermoelectric properties of a material. This information is crucial for various applications, such as thermocouples, which are used to measure temperature in many industries.
Thermocouple images visually represent the temperature distribution across a material and can help identify any potential irregularities or hot spots, which can affect the accuracy of the Seebeck Coefficients measurement.
The Seebeck Coefficient is calculated by measuring the temperature difference between the two ends of a material and the resulting voltage difference. The ratio of these two values is the Seebeck Coefficient, expressed in units of microvolts per degree Celsius (μV/°C).
The Seebeck Coefficients can be affected by various factors, including the composition and purity of the materials used, the temperature difference between the two ends, and the type of contact between the two materials. Other external factors such as mechanical stress and magnetic fields can also influence the Seebeck Coefficients.
