Diminishing in the concentration of quenching defects during thermocycling of orthorhombic TaS3 samples in the temperature range below the Peierls transition temperature T<TP is observed. It makes it possible to study the character of pinning of the charge density wave by these defects. A number of fundamental differences from pinning by ordinary local pinning centers — impurities and point defects — have been found. We conclude that quenching defects are extended (non-local) objects… Expand

Forced Diffusion of Correlated Impurities in the Peierls Conductor o-TaS3
It is shown that in orthorhombic TaS3 with quenching defects, when the temperature changes in the region below the Peierls transition temperature T < TP, forced diffusion of defects arises due toExpand


Properties of strained TaS3 samples in the state of charge density wave and in the normal state
The uniaxial strain of quasi-one-dimensional conductor whiskers of orthorhombic TaS3 at a strain higher than εc ~ 0.8% leads to a sharp increase in the coherence of the properties of a charge densityExpand
Crystal defects influence on peierls transition in orthorhombic TaS3
Abstract The influence of defects in orthorhombic-TaS 3 crystals on Peierls transition, on the threshold electric fields, on the character of the depinning of the CDW is studied. Comparison betweenExpand
Indium doping-induced change in the photoconduction spectra of o-TaS3
Abstract Impurities and defects are known to affect the properties of the charge density wave (CDW) state but the influence of impurities on the density of states inside the Peierls gap remainsExpand
Pinning of charge density waves by irradiation induced defects in orthorhombic TaS3
Abstract Effects of electron irradiation induced damage on dc conductivity, threshold field and complex dielectric constant at 9 GHz are investigated in a wide temperature range. Whereas the singleExpand
Strong-Pinning Effects in Low-Temperature Creep: Charge-Density Waves in TaS 3
Nonlinear conduction in the quasi-one dimensional conductor o-TaS_3 has been studied in the low-temperature region down to 30 mK. It was found that at temperatures below a few Kelvins theExpand
Field-Induced Discommensuration in Charge Density Waves in o-TaS3
We report a synchrotron X-ray study of charge density waves (CDWs) in an o-TaS3 crystal. We found that two independent CDWs coexist in the temperature range of 130 - 50 K. These waves areExpand
Electric field depinning of charge density waves
The pinning of charge-density waves by impurities is considered in systems that exhibit at least short-range order in three dimensions. Impurities are classified into strong and weak with quiteExpand
Dynamics of the charge-density wave. I. Impurity pinning in a single chain
We study the effect of impurities on the dynamics of charge-density waves. At low temperature it is a good approximation to restrict our attention to phase fluctuation only. The competition betweenExpand
Impurity-Induced Pinning,Damping and Metastability of Interchain-Coupled Charge Density Waves
The impurity pinning of the charge density waves that exhibit three-dimensional order due to interchain coupling is investigated in the model of Fukuyama and Lee by taking account of phaseExpand
The dynamics of charge-density waves
In many materials with a highly anisotropic band structure, electron-phonon interactions lead to a novel type of ground state called the charge-density wave. The condensate is pinned to theExpand
