Kurzbeschreibung | This course provides physical foundations to understand the response of different classes of materials to electromagnetic fields, focusing on the dielectric, optical, and magnetic properties of materials, and on the basic functioning of devices that exploit such properties, including photodiodes, photovoltaic cells, LEDs, laser diodes, permanent magnet motors, transformers, and magnetic memories. |
Lernziel | This course aims at giving a deepened understanding of physical phenomena relevant to Materials Science. |
