Interrupted strand model for quasi one dimensional metals

Abstract

Mixed valency planar complex compounds of Pt have been recently identified as quasi one dimensional metals on the basis of a phenomenological model that views the real crystalline compound to consist of a system of collinear metallic strands, each of which is interrupted by a series of insulating lattice defects. An originally defect free strand is thereby replaced by a linear sequence of one dimensional metallic boxes. In the present paper a very simple microscopic formulation of this model is presented. It is applied to discuss such pertinent electronic properties as the density of carrier energy states, the specific heat, the paramagnetic susceptibility and the static dielectric constant.
