Investigating ionic mobility in solid solutions of LixNa1 − xTayNb1 − yO3 via Raman spectroscopy
The ionic mobility in LixNa1 − xTayNb1 − yO3 solid solutions (SSes) is investigated by means of Raman spectroscopy. The average lifetime of an Li+ ion in the equilibrium position and the magnitude of the potential barrier are estimated from the temperature dependence of the line width corresponding to the vibrations of Li+ cations.
