摘要：

This letter reports upon transport properties of the (EDT-TTF)2 [Pd(dmit)2]2 compound. A nonlinear effect is observed below 50 K at ambient pressure. A resistivity bump, observed at ca. 40 K at ambient pressure, is shifted towards lower temperature under pressure and a metallic ground state is stabilized up to 10 kbar. In order to understand lack of superconductivity above 500 mK, low-dimensional electronic correlations are stressed on.
