This course is an elective course that teaches the basic physical principles of semiconductor materials. In addition to the standard semiconductor physics topics, the course also complements the physics of novel semiconductor nanostructures, such as semiconductor quantum wells, quantum dots and two-dimensional materials.In terms of learning, in addition to regular homework and exams, there is a final report at the end of the semester, allowing students to use the knowledge of semiconductor physics they have learned to further independently explore the working principles of various semiconductor devices.
