Black arrows mark laser polarization and blue arrow marks a direction of the graphene ripples. (c) Polar plot showing positions of the 2D peak with polarized light for different laser polarization angle. (d) Raman spectra of two 2D graphene peaks for two different angles of light polarization separated by 90°.

Poznato je da se u takvim sustavima mogu očekivati efekti kolektivnog ponašanja, koji omogućavaju inženjering i dizajn opto-električnih svojstava tim materijala. Dodatno, naša vrlo nedavna istraživanja rezultirala su razvojem materijala koje pokazuju neobičan potencijal za pohranu vodika.
P3. Nanostructural materials for energetic is investigation of preparation, structural properties and application of nano-based materials prepared by magnetron sputtering deposition. The prime interest is investigation of recently invented materials based on self assembled nanoparticles in amorphous matrices. These materials are discovered and developed by our group in the recent few years. They consist of regularly ordered nano-objects of different composition (metallic, semiconductor, and mixed) embedded in various amorphous matrices (alumina, silica, mullite). These materials have a great potential for application in various nanotechnology fields. The most promising applications of semiconductor quantum dots are super-efficient solar cells and photodetectors. Metallic nanoparticles are of great interest for different, today very popular, spintronic applications. The mixed nanoparticles are expected to have some extraordinary properties like electric-field tuneable magnetic properties for the case of semiconductor-metallic mixture. Additional advantage of these materials is regular ordering of nanoparticles in them. It is well known that in such systems are expected some collective behaviour effects, which enable engineering and design of the materials opto-electrical properties. Additionally, our most-recent activities resulted in development of nanomaterials which show extraordinary capability to store hydrogen. These materials are of great interest for energy storage. The main objective of the programme is to become a Croatian center for preparation, characterization and application of these extraordinary nano-based materials. The activities of the programme will be realised under the 3 projects:
