Optoelectronic Properties of Materials

Teaching Methods

During the classes the different topics will be lectured and in the end of the semester a final written exam will be made, a report will be done on a laboratory work performed during at least 3 sessions (9 hours) and the student will present a term paper on a topic of his choice.

Learning Outcomes

The student should: - familiarize with the semiconducting materials and devices and their electronic and optoelectronic applications; - apprehend the relationship between structure and optical and spectroscopic behavior of the different materials, as well as some typical values of their properties, enabling qualitative or semi-quantitative estimates; - understand the operation principles of devices, such as diode junctions, photovoltaic cells, lasers and optical fibers and to appreciate the effects of the size scale (from macroscopic to microscopic and nanoscopic) on the materials properties.
