  author={An-min Zhang and Qing-ming Zhang},
  journal={Chinese Physics B},
Electron—phonon coupling (EPC) in cuprate and iron-based superconducting systems, as revealed by Raman scattering, is briefly reviewed. We introduce how to extract the coupling information through phonon lineshape. Then we discuss the strength of EPC in different high-temperature superconductor (HTSC) systems and possible factors affecting the strength. A comparative study between Raman phonon theories and experiments allows us to gain insight into some crucial electronic properties, especially…
