Electric conductivity and phase diagram of a mixed-stack charge-transfer crystal: Tetrathiafulvalene-p-chloranil

Abstract
The electric conductivity has been measured on the mixed-stack charge-transfer crystal tetrathiafulvalene (TTF) -p-chloranil (CA) as a function of temperature (T>30 K) and pressure (P kbar). On the basis of the experimental results, a P-T phase diagram is presented for the charge-transfer state in TTF-CA.
