Some aspects of charge transport in Li0.5-xNaxLa0.5TiO3 (x = 0, 0.25) ceramics

In this work, the influence of partial substitution of Li to Na in Li 0.5 La 0.5 TiO 3 (LLTO) compound was investigated by broad frequency range impedance spectroscopy (IS). The equivalent circuit method was used to relate the electric modulus spectra with confinement of mobile Li ions by rigidly arranged Na in the lattice of LLTO.
