Synopsis:

The course provides an overview of the basic methods of preparation of quantum structures, with the emphasis on their physical principles, experimental implementation, characteristics and areas of application. Prerequisites include knowledge of solid state physics, theory of solids, and surface physics in the extend of master courses at FJFI. The graduate acquires the theoretical knowledge needed to design and prepare new functional quantum structures with the required properties.

Requirements:
