What Role Does Electron-Phonon Interaction Play in Thermal Conductivity?
Thermal conductivity in materials is mainly governed by phonons. However, electron-phonon interaction can either enhance or impede the flow of heat. In metals, electrons are the primary heat carriers, and their interaction with phonons can lead to thermal resistance. In nanomaterials, controlling this interaction can lead to materials with tailored thermal properties, useful for applications in thermoelectric devices and thermal management systems.
