How Does Electron-Phonon Interaction Affect Electrical Conductivity?
Electron-phonon interaction can scatter electrons, thereby affecting the mobility of charge carriers. In metals and semiconductors, this scattering leads to resistance. At low temperatures, electron-phonon scattering is less significant, but as the temperature increases, phonons become more active, leading to increased scattering and thus higher resistance. In nanomaterials, this effect can be more pronounced due to the increased surface area and quantum confinement.
