Abstract

With a dramatic development of a single crystal growth technique for high purity, high quality nickel phthalocyanine iodide, Ni(Pc)I, we examined th e temperature dependence of the resistivity between 0.9-300 K under pressures between 3 and 14.5 kbar. We found a clear metallic temperature dependence in resistance at all pressures and an insulating phase at low pressures accompanied by a strong non-linear conduction. The conductivity at low temperature exceeded 45,000 S/cm at 14.5 kbar, which is already 7 times higher than the necessary condition to obtain superconductivity in β-(BEDT-TTF)2X salts.
