Dimensionless thermoelectric figure of merit ZT is investigated for two-dimensional organic conductors tau-(EDO-S,S-DMEDT - TTF)(2)(Aul(2))(1+y), tau-(EDT-S,S-DMEDT - TTF)(2)(Aul(2))(1+y) and tau-(P-S,S-DMEDT - TTF)(2)(Aul(2))(1+y) (y <= 0 875) respectively The ZT values were estimated by measuring electrical resistivity thermopower and thermal conductivity simultaneously The largest ZT is 2 7 x 10(-2) at 155 K for tau-(EDT-S S-DMEDT - TTF)(2)(Aul(2))(1+y) 1 5 x 10(-2) at 180 K for tau-(EDO-S S-DMEDT - TTF)(2)(Aul(2))(1-y) and 54 x 10(-3) at 78 K for tau-(P-S S-DMEDT - TTF)(2)(Aul(2))(1 divided by y) respectively Substitution of the donor molecules fixing the counter anion revealed EDT-S S-DMEDT-TTF is the best of the three donors to obtain larger ZT
