The anisotropic electrical conduction behaviour of the textured La2Ti2O7 ceramics was studied using impedance spectroscopy and Seebeck coefficient measurements.

The results reveal that the grain (bulk) conductivity along the perpendicular direction is more than ∼50 times higher than that along the parallel direction below ∼600 °C.

The activation energy (Ea) for conduction is 0.67 eV along the perpendicular direction, much smaller than the 1.45 eV along the parallel direction.

The electrical conduction, along both perpendicular and parallel directions of the textured ceramic, is dominated by p-type hole conduction.

No appreciable contribution of oxide ion conduction to the measured conductivity is observed.
