RESEARCH AREAS and ACTIVITY DOMAINS
• research and development of new materials with functional properties for specific applications;
• Investigation of interface phenomena at micro and nano scale for micro and optoelectronics applications;
• Morpho‑structural, mechanical and phisical‑chemical materials characterization by using the following
advanced techniques:
- X-ray diffractometry in order to identify the crystalline phase of the solid materials powders or
thin films, with the possibility to determine the unit cell parameters (for example: their variation with
temperature, the tension of the network, or because of dopants) and crystallite size, as well as the
tracking of possible changes of crystalline network in the range of temperature: ‑180°C ÷ +1000°C
(in the case of thin films);
- scanning electron microscopy (SEM) which provides viewing and studying of the microscopic
structures and surfaces of different materials types (inorganic, organic, conductive or nonconductive,
magnetic, under the compact structure, powder or thin films);
- atomic force microscopy (AFM) which allows 3D analysis in the nano and micrometric area of
surface topography and detecting the local physical properties such as: electrical resistance, leakage
currents, piezoelectric response, magnetization, elasticity; it is also possible to study the morphology
and the assessment of roughness degree of thin films from organic and inorganic materials deposited
by different methods;
- tunnelling electron microscopy (STM) which allows the study of surface properties from the
microscopic to atomic level, on conductive thin films;
- high resolution electronic microscopy (HRTEM) which allows the study of the properties
and network structures for different materials types (bulk, thin films, wires, powders – all properly
processed up to the electronic transparency level), with crystalline, amorphous or nano‑crystalline
structures;
- determination of the Vickers and Knoop micro‑hardness, and of the Vickers and Brinell
hardness for solid metallic, ceramic, carbonic or polymeric materials;
- X-ray fluorescence spectrometry with wavelength dispersion (WD-XRF);
- atomic absorbtion spectrometry (AAS);
- characteristic X-ray energy dispersive spectroscopy (EDS).
