Research topics

Scientific objectives of the proposal follow recommendation for research directions of the Nuclear Physics European Collaboration Committee (NUPECC), an Expert Committee of the European Science Foundation. More specifically, research objectives of the proposed Center of excellence include:
1) In research of ion beam interaction with matter, to explore processes related to ion impact to materials surface, which are still not well described (such as secondary electron emission and ion desorption), and which strongly depend on projectile type and energy. This is relevant for ion beam analysis techniques, which are sensitive to molecular composition. In the study of processes of charge collection in radiation detector materials, ion induced defects that degrade charge transport properties could also be beneficial and of technological importance as well.
2) In materials research, investigations will be focused on nanoscale changes in the materials followed upon the ion impact. Formation of surface nano-features and modifications of 2D materials (graphene) will be induced by single MeV heavy ions, while higher fluences will be required for investigations of processes that drive ion assisted assembly of nanostructured materials. Future research will clearly benefit from strong momentum those two recently opened research directions have.
3) In nuclear physics research to enlarge understanding of collective phenomena in nuclear structure (nucleon pairing and clustering) and reaction dynamics (multi-nucleon transfers at low energy), interaction between deformed and loosely bound nuclei, structure of neutron-rich nuclei and light nuclei reactions with significant effect on astrophysical phenomena. Important goal is enlarged contribution in development and testing of research infrastructure, including those for experiments at large international laboratories, which is closely related to objectives of other two research groups.

Research topics

The first goal of the proposed NFM is to stimulate research in advanced materials science and engineering through facilitation of inter-disciplinary and multi-disciplinary research groups of the Centre. The proposed researcher activities at NFM for each proposed area in the 5 yrs period is based on the synergetic effect of involved research groups/laboratories based on the focusing on the best existing research thematic as well as by opening of new hot research topics that promise fast developments of scientific excellences and new high technology products. The proposed enhancing of the cooperation of researchers within the Center will be focused within the following three research programmes: 

P1. Silicon nanostructures for advanced applications (leader M. Ivanda)

P2. Sol-gel technology for new functional materials   (leader M. Ristić)

P3. Nanostructural materials for energetic (leader N. Radić)

 

Within the first programme P1. Silicon nanostructures for advanced applications the research will be focused on nanostructural silicon thin films for advanced applications. The Low Pressure Chemical Vapor Deposition (LPCVD) and Physical Vapor Deposition (PVD) developed at Ivanda’s group will be used for deposition thin films and wires of silicon, silicon reach oxide, silicon reach nitride, amorphous silicon, polycrystalline silicon, doping with boron, phosphorus, erbium and europium on flat silicon, quartz glass and alumina substrates as well as on silica microspheres. The porous silicon will be prepared by anodisation process. The structural, optical, electrical and transport properties will be investigating. The research work will be carried out under following projects that will be leaded by M. Ivanda:

T1. Low dimensional silicon for chemical sensing,

T2. Silicon thermoelectric element

T3. Novel silicon based materials for photonics

 T4. Development of new Raman scattering techniques

Within the second programme P2. Sol-gel technology for new functional materials the research on the synthesis of diversity of nanocrystals and nanostructures and their possible applications will be performed. Mechanisms of the precipitation of metal oxides for sensing such as iron oxides and Me-doped iron oxides will be investigated. Novel metallic nanoparticles in the form of colloidal suspensions for biomedical applications will be synthesized and analysed. An apparatus for the synthesis of nanowires will be built. The green-chemistry routes will be used in the synthesis of metal oxide and metallic nanoparticles. Characterization of structural, particulate, and surface properties of the synthesized materials will be performed by well established techniques. The research work will be carried out under following projects:

T1. Nanocrystalline metal oxides for chemical sensing (leader M. Ristić)

T2. Nanoparticles for the use in medical application (leader M. Gotić)

T3. Low dimensional 1D and 2D metal oxides for new functional materials (leader M. Ristić)

T4. R&D of novel multiferroic materials (leader I. Đerđ)

The main goal of the third programme 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:

T1. Semiconductor quantum dots (leader M. Buljan)

T2. Metallic nanoparticles (leader N. Radić)

T3. Materials for hydrogen storage (leader N. Radić)

Research topics

G2D mosaic green_LRThe G2D draws its strength upon synergy of researchers with versatile expertise in condensed matter physics, optics and photonics, soft-matter physics, solid state chemistry, ion-beam physics, and material science. This expertise and synergy provides a promise for discoveries of new phenomena in 2D materials, and potentially their applications. Particular topics to be investigated aim at (opto)mechanical, optoelectronic, spintronic, bioelectronic, capacitor, and photovoltaic applications.

Synthesis

All large scale applications require synthesis (in large amounts) of large area 2D materials. We will explore and improve different methods of synthesis. The CVD method will be exploited under various conditions (vacuum, low pressure, atmospheric pressure) and optimised for the growth of large area (~few cm2) graphene, TMD, and h-BN single-crystal layers on metallic and other types of substrates; we will develop methods of functionalization (modify shapes, electronic properties, etc…) in electronic, optoelectronic and bioelectronic devices. We will develop transfer procedures based on novel carrier polymers and solvents which were not yet exploited, in order to obtain high-quality devices for characterization of optical and (opto)mechanical properties or to obtain high-quality electrode for solar cells. We will also develop mechanochemical methods to synthesize large amounts of 2D material, which offers greater control of the reaction course over traditional methods by establishing novel methods of high-throughput synthesis e.g. for the optimization of graphene anode in supercapacitors. Finally, we plan to produce more complex samples and by this we aim at specific properties and functionality of these complex structures. This will involve production of hybrid structures like DNA arrays on template graphene; samples and devices intercalated by magnetic or other desired proximity property materials; heterostructures obtained by combination of graphene and/or TMD and/or h-BN layers; transparent electrodes for quantum-dots based novel photovoltaic applications; defect engineered graphene and 2D materials.

Characterization

We apply a broad chain of characterization methods aiming at different physical properties. Basic sample characterization is provided through the application of Raman micro spectroscopy (Raman), scanning- and transmission-electron microscopy (SEM, TEM), scanning tunneling and atomic force microscopy (STM, AFM) characterization, and additional techniques, such as x-ray diffraction, or grazing incidence small angle x-ray scattering. In addition, more specialized experiments are envisioned to explore: optical properties of 2D materials (photodetection, photoluminescence, photoexcited carriers); macroscopic elastic properties, e.g. wrinkles and more complicated forms in porous graphite with an experimental insight obtained in newly established Laboratory for extreme mechanics; electronic transport and electronic band structure of different samples by transport methods and photoelectron spectroscopies; efficiency of 2D materials as electrodes in the photovoltaic elements; performance of graphene anode obtained from high-throughput synthesis; porosimetry for samples relevant for gas storing.

Modelling

Theoretical calculations are performed to study various electric, optical and mechanical properties of graphene and 2D materials by using the most up-to-date methods and techniques including DFT calculations (numerical), density-matrix theory calculation of the AC conductivity (perturbation theory), finite-difference time-domain Maxwell equations (numerical calculation of the optical properties of graphene based devices), and theory of elasticity (mechanical properties). In addition, for more complex structures e.g. transistors, electrodes such as gates will be implemented in vdW-DF methodology to model or predict properties of rechargeable batteries, solar cell materials, thermoelectrics and so on.

Associated members

In conjunction with the core team members, G2D research unit of CEMS has a broad network of associated members, starting from the accompanying postdocs, PhD and Masters students and researchers from around who are interested and/or are involved in 2D materials-driven topics. In the G2D unit we plan to employ additional PhD students with well-defined topics which will be aimed to make interdisciplinary connections between different topics embedded in the G2D research.

One of the most important expected impacts of the G2D unit is on young researchers. G2D will form a highly competitive school for training of young researchers with versatile skills, on timely topics, and in stimulating environment nourishing excellence. We are convinced that the students gaining PhD within G2D will be highly attractive as postdocs in top-notch world scientific institutions (for those seeking academic career this is an inevitable step), but also in Croatian SME/industry connected to the G2D and CEMS.
