The unifying characteristic of this Department is nano-characterization used to find correlation of structural, chemical and physical properties of nanostructures, thin films and interfaces. Important basis is unique nano-characterization complex (Omicron qPlus VT UHV AFM/STM, Veeco Nanoscope IV Dimension 3100 with a large variety of modes and NT-MDT NTEGRA AFM combined with Renishaw inVia Reflex Raman microspectroscopy). The research activities concentrate to four research topics, solved in the framework of the national and international projects:
