Abstract
Organic conductor (DMTSA)BF4 is a compound composed of an electron donor DM TSA and a monovalent acceptor BF4-. The conductivity at room temperature is similar to 400 Omega (-1)cm(-1) and behaves metallic. At ambient pressure, the gradual metal-insulator transition was observed at similar to 200K. We found that the sample shows non-linear conduction in the insulating state under 0.35GPa. We discuss the apparent similarity with the non-linear elect ric conduction by the density wave sliding.
