Department
Entry knowledge
Atomic Physics, Quantum Physics, Solid State Physics, partially Statistical Physics and Thermodynamics.
Rules for evaluation and completion of the course
The assessment of a student is made upon a quality of a discussion on topics selected at the colloquium (lecture notes allowed at preparation).
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.
Aims
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.
