Abstract

The electrical conductivity (σ) and thermoelectric power (S) for the system La1−x Nd x TlO3 (0 ⩽x⩽ 1.0) in the temperature range 295 to 805 K are reported. Both logσ andS as a function ofT have been found to be linear with a break in the slope around a specific temperature,T B. The break temperature systematically decreases as we proceed from the systemx=0 tox=1.0. It has been concluded that conduction belowT B is extrinsic and takes place owing to hopping of electrons localized on the defect centre Tl2+ to Tl3+ on normal sites. Conduction aboveT B is the normal band type in all systems. The energy band gap has been evaluated in all cases and it has been found that it decreases systematically fromx=0 tox=1.0.
