Interchain interactions of quasi-1D CDWs

Sažetak
An X-ray study of the quasi-one-domensional charge density wave (CDW) system (NbSe_4)_10I_3 as a function of temperature from room temperature down to 130 K has been performed by taking oscillation and zeroth level Weissenberg photographs. A reversible transformation of the room temperature tetragonal lattice into four symmetrically-related monoclinic domains has been observed at the Peierls transition temperature, T_P = 285 K, with a continuous change of the monoclinic angle from 90^0 to 92.1^0 at 130 K. The monoclinic deformation of the tetragonal lattice, i.e. the shear-strain along the chain axis seems to be an elastic response to the long wavelength transverse modulation of the 3D-CDW order which can be qualitatively explained by taking into account the Coulomb interaction between CDWs on neighbouring chains up to the next-nearest-neighbours.
