Abstract

Transport properties of a strongly correlated organic conductor (CHC +)TCNQ - were examined under high pressures up to about 7 GPa using a diamond anvil cell, where CHC + denotes hemiprotonated cytosine pair and TCNQ represents 7,7,8,8-tetracyanoquinodimethane. This salt is a highly conductive semiconductor as a fully ionic TCNQ salt with the activation energy E a of 0.14 eV at ambient pressure. Application of high pressure gradually increased the conductivity. The E a decreased monotonically by a rate of 0.013 eV/GPa.
