Abstract: In order to compare the carrier dynamics and reveal the origin of differences in their electrical behaviour, time-resolved reflectivity changes were measured on single crystals of the title compounds. The observed relaxation behaviour well explained their electrical behaviour, and indicated that different conduction mechanisms dominated κ-and λ-type BETS salts, irrespective of local spins, at ca. 8-100 K; the electrical behaviour of the κ-type salts is governed by relaxation times of carriers and/or density of states at the Fermi levels, while that of the λ-type salts is dominated by the latter.
