Department of Condensed Matter Physics (KFKL)

The Department main mission is the research and education in the field of solid state physics with emphasis on electronic properties of materials. This mission is realized by a broad spectrum of experimental and theoretical research topics with an essential involvement of students and intensive international collaboration, including active participation in European large research infrastructures.

Offer
