Aim
The course uses concepts from electromagnetic field theory, quantum mechanics and atomic physics. The origin of the electronic structure of solids is discussed based on theories developed in previous courses. Emphasis is on the bandstructure and electrical properies of semiconductors, which naturally leads to the introduction of the pn junction. Transistors are briefly discussed. The course syllabus also includes an overview of optical and magnetical properties of solids. Concepts treated in the course are relevant for instance in the rapidly developing fields of nanoscience and nanotechnology, which is illustrated throughout the course.

Knowledge and understanding
For a passing grade the student must

• be able to describe the physical models used in the course as well as their prerequisites, possible applications and limitations.

• be able to explain how differences in electrical properties arise.

• be able to discuss possibilites and limitations of semiconductor materials.

• be able to describe the pn junction and some semiconductor-based electronic components.

• describe some electronic and optical properties of solids and discuss these properties based on the models included in the course.

Skills and abilities
For a passing grade the student must

• be able to chose relevant models with elements of quantum mechanics to describe the electronic structure of solids.

• be able to carry out and evaluate experimens and write a laboratory report

• be able to present and discuss problems and experimental results in writing and in oral presentations.
