Comprehensive transport studies of anisotropy and ordering phenomena in quasi-one-dimensional (TMTTF)2X salts (X = PF6, AsF6, SbF6; BF4, ClO4, ReO4)

Abstract

The temperature dependent dc resistivity of the quasi-one-dimensional organic salts (TMTTF)2X ( X = PF6, AsF6, SbF6; BF4, ClO4, ReO4) has been measured in all three crystal directions in order to investigate anisotropy, localization effects, charge and anion ordering phenomena at low temperatures. For all compounds and directions we extract the transport mechanisms in different regimes. The data are thoroughly analyzed, related to structural properties, and extensively discussed in view of previous studies and latest theories. It becomes apparent that the anions have a severe influence on the physical properties of the TMTTF salts.
