Explore advanced thermodynamics concepts in this comprehensive lecture focusing on relative diffusion fluxes and thermoelectric effects. Delve into the physics of energy and entropy carried by photons in electromagnetic radiation, and master the principles of thermoelectric phenomena in solid conductors. Learn about the Seebeck effect and its applications in thermocouples and thermoelectric generators, understand the Peltier effect's cooling and heating capabilities, and distinguish between Thomson heating/cooling and Joule heating. Examine Onsager cross effects, the Curie symmetry principle, and the relationships between independent diffusive fluxes. The lecture concludes with modern applications in charge and spin current transport, including the spin-Seebeck effect. For optimal learning efficiency, viewing at 1.5x speed is recommended by the instructor.
