Abstract

(TaSe4)2I is a quasi-1 D conductor which undergoes a Peierls transition at Tp = 260 K [1]. Phonon softening at 2kF (Fermi momentum) induces lattice modulations associated with an electron charge density wave (CDW). Elastic singularities at the Peierls transition are not yet well understood [2]. The associated singularity in the sound velocity examined theoretically by Nakane [3] varies like |T-Tp|−1/2 around Tp.
