Postdoctoral Fellow in the Laboratory of Nanomaterials

Nuclear Physics Institute of the CAS announces a vacancy for the position of

Postdoctoral Fellow in the Laboratory of Nanomaterials

Job description:

We announce that a new postdoctoral position is open to complement the Laboratory of Nanomaterials (Group of Materials Research with Neutron and Ion Beams - MRNIB) dedicated to the study of new materials with neutron and ion beams. The main projects on which the group is currently working include the synthesis of binary and ternary composites (MAX phases and MXenes), thin layers of hybrid materials (with fullerenes and transition metals), thin all-solid-state lithium ion batteries (ASSLIB), heterogeneous sensors of hazardous gases, and biosensors based on etched ion tracks in thin polymers. The group is also involved in the fundamental study of exotic nuclear reactions, and diffusion, and concentration/depth diagnostics of elements in complex material systems. Finally, the group is also dedicated to development of new deposition, irradiation and nuclear analytical methods.

We will require that the newly admitted member fully participates in all group activities and demonstrates appropriate ability, erudition and independence in solving the tasks set in the group. The group is involved in grant projects, so it is assumed that the new member will also be assigned important tasks in any new grants.

 

Laboratory of the group:

The laboratory of the MRNIB group is equipped with low-energy ion facilities (Duoplasmatron and LEIF), which currently provide ion beams with an energy of up to 35 keV, and which are used for material deposition (using an ion sputtering technique) and its controlled modification (by high-frequency ion beam bombardment). The deposition of nanostructures (epitaxial films and nanocrystals) is carried out on the new Molecular Beam Epitaxy (MBE) system, the synthesis of hybrid composites on an upgraded Univex device. Analysis of the sample morphology is performed on an atomic force microscope (AFM) equipped with a vacuum kit, external magnets and annealing cells. In cooperation with the Laboratory of Tandetron, an ion beam analysis (IBA mathods, concentration and depth profiling of elements) of the samples and their modification (by implantation or irradiation) using MeV-energy ions can be carried out.  The group also has at its disposal several analytical methods (NDP, PGAA, neutron radiography) on a thermal neutron beam filtered by a neutron-guide installed on a horizontal channel of the LVR15 reactor (operated by the CV Rez). Vacuum furnaces, electrochemical stations, evaporators, etc., are additional auxiliary equipment used to perform treatments and further examination of the samples.

Nuclear Physics Institute of the CAS announces a vacancy for the position of

Senior Scientist in Laboratory of Tandetron, Department of Neutron Physics 


We have an open position for someone to complement our existing group dealing with ion beam modification and synthesis of nano and microstructured materials, radiation defect evolution study in 2D materials and other materials, radiation hardness testing and modification of nuclear materials in general by energetic ion beams, ion beam technology and instrumentation for ion beam analytical methods, ion beam elemental tomography etc. We are looking for independent senior scientist which will strengthen our team in the newly funded project devoted to multiscale materials and their development, synthesis by energetic ion beams for bioapplication, sensorics, optics and electronics.

 

Our Laboratory of Tandetron (LT)

The medium-current (MC) version Tandetron with a maximum terminal voltage of 3MV is used for the production of ion beams with energies in the range from 600 keV to about 30 MeV. Ions typically from H+ up to Aun+ are available for ion-beam analysis and ion implantation depending on the ion-charge state. The LT is equipped with Rutherford backscattering spectrometry (RBS), RBS-channelling, elastic recoil detection analysis (ERDA), ERDA with a time-off light (TOF) spectrometer, particle-induced emission of X-rays (PIXE), PIXE-channelling, particle-induced γ-ray emission (PIGE). High-energy ion-beam implantation/irradiation end stages and ion-microprobe lithography are employed for the nano- and microstructure synthesis and modification of materials to obtain new functional properties. An ion-microbeam system equipped with a newly designed bigger chamber with a detector array is used for 3D elemental mapping using PIXE, PIGE, RBS; for single ion-beam irradiation; for structural studies of internal morphology via scanning transmission ion microscopy (STIM) analysis and ion lithography with medium heavy ions. Moreover, the LT is equipped with a small deposition and complementary analytical laboratory including layer deposition techniques (CVD, a two-magnetron sputtering system for various coating depositions, a laser source for the irradiation, ablation and microstructuring of the solid phase, spin coating for polymer nanocomposite deposition) and analytical methods (optical ellipsometry, optical analysis in the UV–Vis–NIR wavelength range).

The above described instrumentation portfolio is used among others in synthesis and characterisation of the nanostructures for optics, spintronics and photonics by means ion beams at Tandetron accelerator. The main research directions of the Laboratory of Tandetron (LT) include the preparation and characterisation of micro- and nanostructured materials, which are of interest for basic and oriented research in material, environmental and biomedical sciences. Ion-beam analytical (IBA) methods are employed in the investigation of materials coming from material research, industry, micro- and nanotechnology, electronics, optics and laser technology, and in chemical, biological and environmental investigation in general. We thoroughly improve the instrumentation of the LT to make it competitive in the European scientific space and to enlarge the portfolio of our ion-beam instruments. We have a very fruitful collaboration with several excellent ion-beam centres in Europe (Helmholtz-Zentrum Dresden-Rossendorf, Germany; Ion-Beam Centre of the Hungarian Academy of Sciences, ATOMKI, Hungary, etc., Brookhaven National Laboratory, USA etc.). The LT is closely connected to other ion-beam centres in Europe, mainly to the RADIATE consortium, unifying the most important ion-beam centres in Europe.
