Abstract

Charge-transfer complexes such as TTF-TCNQ have been the center of intensive research because of their high electrical conductivity, which is close to that of metals. Therefore, any understanding of these interesting materials, as well as a meaningful discussion about future progress in their research, requires some understanding of the mechanism giving rise to the electrical resistivity. Nevertheless, the understanding of the resistivity has not been in the center of research in this field. Still, several conflicting theories have been proposed to account for the resistivity, and caused quite a measure of controversy. In contrast, the experimental situation is far more satisfying. The electrical resistivity, its temperature and pressure dependence, is by now well established. Experiments on the frequency dependence and the effect of radiation damage exist. The Hall mobility and magnetoresistance have been investigated; related transport phenomena, such as thermoelectric power, heat conductivity, and spin diffusion are known. A rather large number of high-conductivity charge transfer complexes are by now known. Recently Shubnikov-de Haas oscillations were seen in HMTSF-TCNQ, providing the most striking evidence for the metallic nature of this substance.
