Seebeckkerroin

Seebeckkerroin, also known as the Seebeck coefficient, is a fundamental material property that describes the voltage generated across a material when there is a temperature difference across it. This phenomenon, known as the Seebeck effect, is a cornerstone of thermoelectricity. The Seebeck coefficient is typically measured in units of volts per Kelvin (V/K) or microvolts per Kelvin (µV/K).

A positive Seebeck coefficient indicates that the material is a p-type semiconductor, meaning that the majority charge carriers are holes. In this case, the voltage will be generated in the direction of increasing temperature. Conversely, a negative Seebeck coefficient signifies an n-type semiconductor, where electrons are the majority charge carriers. For n-type materials, the voltage is generated in the direction of decreasing temperature.

The magnitude of the Seebeck coefficient is crucial for thermoelectric applications, such as power generation and cooling. Materials with a high absolute Seebeck coefficient are desirable for efficient thermoelectric devices, as they can convert a larger fraction of thermal energy into electrical energy or vice versa. The Seebeck coefficient is influenced by factors such as the material's composition, crystal structure, and doping levels. Understanding and controlling the Seebeck coefficient is essential for optimizing the performance of thermoelectric generators and coolers.
