Université de Tours - GREMAN

Isabelle Monot-Laffez is currently professor at the GREMAN Laboratory, University of Tours (France). For more than 20 years, in CRISMAT Caen and ISTEC Tokyo and since 2000 in Tours,  her research activity is focused on solid state chemistry, especially the synthesis and characterization of oxide materials with remarkable properties (superconductors, magneto-resistive, piezoelectrics oxides, …) in the form of ceramics (conventional or SPS) or single crystals grown by zone melting.She has published 85 articles in international reviews and more than 40 communications. She was director of an institute of technology (IUT of Blois) during ten years (2003-2013). She is deputy director of GREMAN laboratory since 2016, and of the board of the doctoral school. 

Abstract

Sodium potassium niobate (K,Na)NbO3 (KNN)lead free perovskite ferroelectrics have focused broad interest since early 2000 in order to replace in certain applications the lead-based ferroelectrics, predominantly Pb(Zr,Ti)O3.... [ view full abstract ]
