Physics of Electronic Components

The course progressively presents the main physical phenomena that allow us to understand the functioning of electronic components and their use in electronic circuits. The first part introduces the physics of semiconductor materials and then deals with the characteristics of equilibrium materials in the second part. The third part presents the main phenomena of electronic transport. Finally, the fourth and fifth parts present the most important electronic components: diodes and transistors.

The aim of the course is to provide students with a basic understanding of the main characteristics and limitations of electronic components. 

By combining various concepts drawn from solid-state physics, quantum physics and semiconductor physics, students will be able to acquire the knowledge essential for understanding the operation of current and future electronic components.
