摘要：

The influence of interband transitions resulting from charge fluctuations between different CuO2 layers on infrared active phonons in high temperature superconductors is calculated. Under special conditions in the superconducting state a two-peak structure of the phonon with rapid variation of the oscillator strength is found. This may explain recent far-infrared experiments on Tl2Ba2Ca2Cu3O10. © 1990.
