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 Ea of 0.14 eV at ambient pressure. Application of high pressure gradually increased the conductivity. The Ea decreased monotonically by a rate of 0.013 eV/GPa.
