Photodetectors

This course is devoted to the understanding of the physics behind the operation of photodetectors and to describe in detail the state-of-the-art light detectors used nowadays in research and industry.

The main topics of the course are the following:

1. General properties of photodetectors

2. Vacuum-based photodetectors

3. Solid-state photodetectors

4. Applications
