The 1D organic salt TTF[Ni(dmit)2]2 becomes superconductor with Tc=1.6 K under an applied hydrostatic pressure of 7 kbar. Structural determinations in this system lead us to suspect that superconductivity (SC) coexists with a charge density wave (CDW) instability at low pressure. In order to better understand how SC emerge from a CDW and to revisit the pressure–temperature phase diagram of the TTF[Ni(dmit)2]2 we performed transport and thermoelectric power measurements under pressure.
