dc.description.abstract | We present measurements of the infrared response of the quasi-one-dimensional organic conductor (TMTSF) 2FSO 3 along (E∥a) and perpendicular (E∥b') to the stacking axis as a function of temperature. Above the metal-insulator transition related to the anion ordering the optical conductivity spectra show a Drude-like response. Below the transition an energy gap of about 1500 cm -1 (185 meV) opens, leading to the corresponding charge transfer band in the optical conductivity spectra. The analysis of the infrared-active vibrations gives evidence for the long-range crystal structure modulation below the transition temperature and for the short-range order fluctuations of the lattice modulation above the transition temperature. We also report about a new infrared mode at around 710 cm-1 with a peculiar temperature behavior, which has so far not been observed in any other (TMTSF) 2X salt showing a metal-insulator transition. A qualitative model based on the coupling between the TMTSF molecule vibration and the reorientation of electrical dipole moment of the FSO 3 anion is proposed, in order to explain the anomalous behavior of this new mode. © EDP Sciences/Società Italiana di Fisica/Springer-Verlag 2007. | * |
