Learning unit contents

Functionals (or "smart") materials are those materials that, due to their specific properties (dielectric, piezoelectric, ferroelectric, ferromagnetic, magneto-electric, electro-optic, ...) are playing an active role in devices such as memories, sensors, actuators, transducors and are in the heart of technological applications. The course will focus on the family of ABO_3 oxide with a perovskite structure which play a key role in numerous applications and due to their diversity allow considering various properties.  Chapiter 1 will focus on the atomic structure of these compounds; it will target the identification of structural instabilities they can develop and the various types of phase transitions these instabilities can produce.  Chapiter 2 will show how to model such structural phase transitions in the generic framework of Landau theory.  Chapter 3 will address the question of finite size effects in nanostructures of these compounds. Chapter 4 will propose a more microscopic description of these compounds in order to put in perspectives the structural and electronic properties. The course will be accompanied with exercices targetting the prediction in the context of Landau theory of the properties of selected oxides under applied mechanical and electric constraints.

Learning outcomes of the learning unit

The goal of this course is to provide to the student a microscopic understanding of the origin of coupling properties in functional materials.

Prerequisite knowledge and skills
