Description
This course provides a step-by-step introduction to the key physical phenomena necessary for understanding how electronic components work and how they are used in electronic circuits. The first part introduces the physics of semiconductor materials, followed by the second part, which covers the characteristics of materials at equilibrium. The third part covers the main phenomena of electron transport. Finally, the fourth and fifth parts present the most important electronic components: diodes and transistors.
Objectives
The objective of the course is to provide students with the fundamentals needed to understand the main characteristics and limitations of electronic components.
By combining various concepts from solid-state physics, quantum physics, and semiconductor physics, students will gain the essential knowledge needed to understand how current and future electronic components work.
