Problem formulating. The quasi one-dimensional conductor TaS3 of the orthorhombic modification shows strong electromechanical coupling of the sliding charge density wave (CDW) with the lattice of crystals. However, until now the effect of the dynamic deformation of the sample on the CDW sliding has not been studied. Goal. Search and study of a new effect: the influence of sample vibration on CDW dynamics. Result. The conductivity of TaS3 samples is studied as a function of the electric field and the frequency of mechanical deformation of the sample. It is found that when the vibration frequency of the piezoelectric actuators deforming the sample coincides with one of the mechanical resonances of the sample, suppression of the threshold field and features in the form of Shapiro steps are observed on the I–V characteristics. The effect is similar (though not equivalent) to that of RF voltage applied directly to the sample at the same frequency. Evidence is provided that these features are not coupled with the effect of electrical interference. Practical meaning. The result opens up a new area of electromechanical effects in quasi one-dimensional conductors with CDW and can be used for detecting and processing of mechanical oscillations in the microwave range.

Order Of Magnitude

Recently-discovered high-temperature superconductors border on a Mott metal insulator transition; pure La2CuO4 undergoes a commensurate charge-density-wave transition and becomes an insulator. At other compositions, the incipient charge-density wave causes a drastic softening of those plasmon modes with wave vectors connecting points on the Fermi surface. These soft plasmons (typically tenths of an electron-volt) serve as the attraction which binds Cooper pairs, instead of the usual phonons. Consequently, transition temperatures are an order of magnitude larger than for phonon-induced superconductivity. One of the factors responsible for the strong electron - plasmon coupling is the influence of the empty f-orbitals of La or Ba.
