Organisation and examination

Teaching in the first semester, review in January

Units courses prerequisite and corequisite

Prerequisite or corequisite units are presented within each program

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 and start with a review of the extremely various properties exhibited by these compounds nevertheless sharing the same structure. It will introduce first-principles (DFT), semi-empirical (effective Hamiltonians) and phenomenological techniques allowing the theoretical description of functional materials. It will then discuss the microscopic origin of various coupling properties as well as their temperature dependence. The course will describe applications in the fields of electronics and sensing. It will also mention the influence of finite size effects in nanostructures and the computational design of artificial materials with optimized properties.

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.
