Learning outcomes of the course unit

Student gets a wide knowledge on basic technologies for fabrication of nanoscale materials and nanostructures, about analytical techniques and related physical principles. Finally, current and future applications in devices are presented as well.

Prerequisites

Atomic Physics, Quantum Physics, Solid State Physics, partially Statistical Physics and Thermodynamics.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures. Teaching is suplemented by practical laboratory work.

Assesment methods and criteria linked to learning outcomes

The assessment of a student is made upon a quality of a discussion on topics selected at the colloquium (lecture notes allowed at preparation).

Aims

The emphases will be put to qualitative analysis of physical phenomena, explanation of basic properties of solids using microscopic models and of physical principles of selected experimental methods common in research of materials.

Specification of controlled education, way of implementation and compensation for absences

The presence of students at practice is obligatory and is monitored by a tutor. The way how to compensate missed practice lessons will be decided by a tutor depending on the range and content of the missed lessons.
