Optical, Electrical and Magnetic Characterization Techniques

The course is taught normally every other year.

The objective is to provide students with a broad and deep understanding of the principles of optical, electrical and magnetic characterization techniques used in research and development of emerging electronic and photonic materials and devices.

Starting from the concept of probe-target interaction, the course gives insights into some of the most widespread used characterization techniques in nanoelectronics, photonics and solid-state physics. A theoretical framework is provided, in which basic phenomena involving electromagnetic radiation and charged particles are described and presented as means to access to a plethora of physical quantities. As photon-matter interactions are concerned, effects such as elastic scattering, diffraction, absorption, phase/polarization perturbation, photo-emission and photoelectric effect are addressed and discussed in relation to relevant techniques. As for charges-matter interactions, cathodoluminescence, electron scattering, absorption and diffraction, ion-induced photoemission are introduced and discussed in relation to relevant techniques. In the course, the main limitations and advantages of the presented characterization techniques will be discussed, particularly referring to specific application domains such as sensing and optoelectronics.
