Abstract

The effect of the electric field on one of the Raman phonons (~285 cm−1) is studied in the chargedensity-wave state of orthorhombic TaS3. The phonon frequency decreases when the field exceeds the threshold for non-Ohmic conduction. Several mechanisms which may lead to phonon softening in the current-carrying state are considered.
