Abstract
The observed structural phase transitions in tetrathiafulvalene-tetracyanoquinodimethane (TTF-TCNQ) are analyzed using a Landau-Ginzburg-type free energy. It is shown that because of a coupling between the components and of the wave vector associated with the charge-density wave, the latter is expected to be nonzero for °K, contrary to previous expectations.
