Raman spectroscopy experiments show that the interaction between electrons and phonons in graphene resembles the Dirac fermion–photon coupling in quantum electrodynamics. In the early days of ...

The motion of the selenium atoms (red) changes the energy of the electron orbitals of the iron atoms (blue), and the resulting electron vibrations are recorded separately with a technique called ...

This strong electron-phonon coupling provides a mechanism for the enhancement of superconductivity transition temperature in ultrathin FeSe. Xiaoqing Pan, Study Lead Author and Distinguished ...
