Research Activity

The research activities of this group, (Lab for Thin Films- Nanosystems & Nanometrology- LTFN) involve:
1. Growth and study of nanomaterials and thin films on 2D and 3D substrates in high and ultra high vacuum environment with the use of Physical Vapor Deposition- PVD
2. Surface engineering of inorganic and organic materials with the use of ion bonds and plasma
3. Study of optical and electronic, structural and nanomechanical properties of thin films and bulk materials with state of the art techniques (such as Spectroscopic Ellipsometry, X ray diffraction and reflection, Atomic Force Microscopy and Nanoidentation).
4. Development of in-situ and real-time optical monitoring methods of atomic processes and interactions that take place during films growth or surface modification and activation.

The scope of the above mentioned activities is the development of the research in basic level (understanding the growth mechanisms of the thin films and nanostructures, correlation of the structure of thin films and nanostructures with the optical- electronic- mechanical properties, computational methods and techniques) and also application level.
The applications include new advanced materials for microelectronics, flexible electronic devices, photovoltaics, barrier in gas nanocoatings for flexible packaging, hydrogen sensors and biosensors, coatings for medical implants and biocompatible materials etc.
