The integration of cutting-edge science and technology into undergraduate teaching is an important route to realize professional knowledge from learning, application to innovation. In this paper, the scientific research of thermoelectric materials is integrated into the teaching of solid physics, in which the research frontier of thermoelectric materials can promote the teaching and thinking of basic knowledge in solid state physics, such as crystal structure, crystal combination, crystal thermal properties, free electron theory and energy band theory. It aims to strengthen students^, understanding of the basic knowledge of solid state physics, stimulate learning interest, expand the level of knowledge, cultivate students^, scientific thinking and ability to use the basic knowledge to solve practical problems, and effectively improve the teaching quality of solid state physics course.
