Summary:
The Seebeck coefficient, also known as the thermoelectric voltage or thermopower, is a measure of the voltage generated by a material in response to a temperature gradient. It is an important property of materials used in thermoelectric devices, which convert waste heat into electricity.

The strain dependence of the Seebeck coefficient refers to how the value of the coefficient changes when the material is subjected to mechanical strain. In this article, the authors describe an apparatus they have designed for measuring the strain dependence of the Seebeck coefficient in single crystals.

The apparatus consists of a sample holder that can be mechanically deformed to apply strain to the sample, and a measurement system that determines the thermoelectric voltage generated by the sample as it is subjected to different levels of strain. The authors describe the details of the design and operation of the apparatus, as well as the results of experiments using the apparatus to measure the strain dependence of the Seebeck coefficient in various materials.

Overall, the article discusses the development and use of a specialized tool for studying the relationship between mechanical strain and thermoelectric properties in single crystals.
