Research and development of new functional materials and nanostructures in Molecular Physics Laboratory has been undertaken in the framework of several research topics:

1. silicon nanostructures for advanced applications
2. new ceramics and multiferroics
3. molecular systems and vibrational analysis
4. laser interactions and selforganizational processes
5. new methods for Raman spectroscopy
6. tittania nanostructures

The research topics

The research is focused on nanostructural silicon thin films for advanced applications. The Low Pressure Chemical Vapor Deposition (LPCVD) and Physical Vapor Deposition (PVD) were implemented and developed at Ivanda’s group.

The different type of silicon based thin films are preparing like silicon reach oxide, silicon reach nitride, amorphous silicon, polycrystalline silicon, doping with boron, phosphorus, erbium and europium; porous silcon by electrochemical etching.

The structural, optical, electrical and transport properties are investigating with a goal of development of doped silicon nanostructured films (dots, wires, porous structure) for thermoelectric elements (Peltier cooler and heater, low temperature sensor); silicon nanocrystals thin films doped with rare earths for photonics (spherical microresonators, optical amplifiers, lasers); and porous silicon for gas and/or chemical sensing.

Beside, different aspects of Raman scattering as a powerful analytic tool has been developed: low frequency Raman scattering for determination of size distribution of nanoparticles, portable Raman spectrometer as well as new  techniques for SERS spectroscopy.
