Lattice Structure and Instabilities and Electron—Phonon Coupling in Superconductors with High Transition Temperatures

  • P. Hertel


Observations, particularly in high-temperature superconductors, show lattice instabilities and anomalies in the phonon spectra.1 In addition, metastable systems, for example, thin films, show a high T c .
