The lecture should enable basic orientation in modern solid-state physics, in physical mechanisms determining
and influencing basic properties of solid materials. In particular, the lecture deals with crystal structure of solids,
with a response of a solid to an external interaction (mechanic, electric, magnetic), self-organization processes
leading to ferroic phases, elements of the electron theory of solids and thermal properties of solids. In the lecture,
phenomenological, thermodynamical, statistical and quantum-mechanical methods of description are used.

To participate in the exam it is necessary to complete the credit. The exam contains written and oral part; Written part rests on solving a simple problem (max. 30 min). Oral part is partially based on the problem solution (takes ~45min.). Total evaluation summarizes both written and oral part. Exam requirements follow the subject syllabus as presented during lectures. Last update: Carva Karel, doc. RNDr., Ph.D. (12.05.2022)
