This paper reviews the role of defects and dopants, including their dynamics, on the properties of barium titanate, the most widely used ferroelectric ceramic  in electronics.

Written by Clive Randall , a world-wide recognized scientist and Director of the Materials Research Institute at The Pennsylvania State University, and his PhD student Pedram Yousefian, it is an essential reading for understanding the application of BaTiO3 in MLCCs and future opportunities offered by this material.
