“…In a series of elegant transport measurements on the semimetallic CDW conductor, NbSe 3 [1], the Cornell group has shown how phase-slip is driven by longitudinal strains in the CDW [4]. The strain profiles they deduced have been qualitatively verified with x-ray diffraction [5] and infrared electro-optic measurements [6]. The latter measurements, the subject of this paper, were done on semiconducting K 0.3 MoO 3 (blue bronze) [7].…”

In recent measurements on the charge-density-wave (CDW) conductor blue bronze (K 0.3 MoO 3 ), the electro-transmittance and electro-reflectance spectra were searched for intragap states that could be associated with solitons created by injection of electrons into the CDW at the current contacts [Eur. Phys. J. B 16, 295 (2000); ibid 35, 233 (2003)]. In this work, we adapt the model of soliton absorption in dimerized polyacetylene to the blue bronze results, to obtain the (order of magnitude) estimate that current induced solitons occur on less than ~ 10% of the conducting chains. We discuss the implications of these results on models of soliton lifetimes and motion of CDW phase dislocations.

“…In the context of CDW dislocations models where the CDW is viewed as an electronic crystal and nonlinear conductivity arises from a plastic flow of CDW dislocations [17][18][19][20][21], it can be shown that, for surface pinning E t αK perp. /t where K perp.…”

“…Application of a voltage larger than threshold causes the CDW to become compressed at the positive contact and rare"ed at the negative contact. The density of the CDW condensate is two electrons per wavelength per chain, so that compressions (rarefactions) are negatively (positively) charged (28). A detailed examination of the spatial dependence of the electromodulated transmission showed that ¹/¹J*/*z (17).…”
