| Course 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. |
|
| Course objective : | The goal of this course is to provide to the student a microscopic understanding of the origin of coupling properties in functional materials. |
|
| Prerequisites : | Physics of materials (course PHYS0936) |
|
| Workshops : | not appropriate |
|
| Organization : | The oral course will content 10 modules of 2 hours and will be completed by 5 modules during which the student will play a more active role (exercises, computer simulations, reading of articles). |
|
| Written notes : | Notes will be distributed to the students. |
|
| Assessment : | Oral exam after a written preparation |
