Studies of mixed electronic-ionic conductors in BEDT-TTF family compounds

Some of the salts of BEDT-TTF (or ET) family namely ET2Cu5I6, ET3CuCl4xH2O and ET3AgxI8 are good mixed electron- group Ib ion conductors. Due to the presence of frozen disorder in anion layer none of the salts is a superconductor, though the first two remain metallic properties down to lowest temper...

Description
Summary:Some of the salts of BEDT-TTF (or ET) family namely ET2Cu5I6, ET3CuCl4xH2O and ET3AgxI8 are good mixed electron- group Ib ion conductors. Due to the presence of frozen disorder in anion layer none of the salts is a superconductor, though the first two remain metallic properties down to lowest temperatures. Disorder and non stoichiometry effect on electron transport properties of ET2Cu5I6 compound have been studied. ESR studies of ET2Cu5I6 salt show that the line width is strongly increased by the disorder.
