- Abstract
- Polaronic absorption features, induced by excess charges in both electron and hole doped
cuprates, have been measured. The features here reported include additional phonon-like
peaks in the far infrared and a broad overtone band centered at ~1000 cm -1 (d band). The
peaks in the far infrared are attributed to local modes. The d band is produced by overtone
and combination bands of a few of these local modes and is well fitted in a polaron model. Most
of these polaronic contributions survive in the metallic phase, where they are superimposed on
the Drude term due to free carriers. (literal)
