1. Each student is assigned a sub-chapter of the main textbook of the course (Optical Properties – Mark Fox) that has not been discussed in the lectures and delivers a powerpoint presenting the material as a 45-min lecture, followed by 30 minutes of questions by the instructor/other students (40% of the grade)
2. Each student produces a ~10 page bibliographical essay accompanied by a 45 minute presentation plus 30 minutes question time, on a specialized topic or a specific publication related to optical properties of semiconductors assigned by the instructor (60% of the grade)
