Growing processes of Nanostructures in (Nd,Li)TiO 3

Abstract

We have investigated correlation between nanostructures and ion-conducting properties in Nd_2/3-xLi_3xTiO₃ by a transmission electron microscopic experiments, combined with the conventional ion-conducting measurement. We found different types of nanoscaled domain structures such as the chessboard-type and diamond-type nanostructures in Nd_2/3-xLi_3xTiO₃ (x=0.14). Formation of these nanostructures depends strongly on the sample preparation conditions, in particularly cooling rate from the sintering temperature.
