Technology has been tremendously advancing every day. Among these advancing fields growth in the field of functional electronic materials is very steep and even rapid than the predictions (Moores law). Ferroelectric materials belong to the most renowned families of functional materials. These materials are at the peak of research and have dragged the attention of technologists and researchers because of their excellent piezoelectric, pyroelectric and non-linear optical properties. Over years, many ferroelectric materials are developed, synthesized, fabricated, characterized and exploited for...
