Abstract

We examine two proposed models of the observed charge ordering (CO) in the quasi-1D, 1/4-filled organic charge transfer solids. The models are characterized by the site charge densities ..1010.. and ..1100.. respectively. Using a Peierls-extended Hubbard model to include both electron-electron and electron-phonon interactions, we show that 1) the ..1010..CO can occur only when the nearest-neighbor Coulomb repulsion is sufficiently strong; 2) a spin-Peierls state can coexist with the ..1010..CO; and 3) experimental evidence clearly supports ..1100.. CO in the (TMTSP) and the 1:2 anionic CTS, while in the (TMTTF) salts the nature of the order is not yet clear.
