Head of Laboratory : Dr. Corneliu Ghica

     This laboratory is mainly committed to structural investigations by advanced characterization methods such as analytical transmission electron microscopy (TEM), electron paramagnetic resonance (EPR), Mössbauer spectroscopy. The research activity includes, also, synthesis of nanostructured materials by the hydrothermal or co-precipitation methods. Other important research subjects are related to the gas sensing and photocatalysis fields.
     Among the important research equipments we mention: two analytical transmission electron microscopes, a SEM-FIB dual analytical system, five EPR spectrometers operating in several microwave bands and working modes down to liquid He temperature, three Mössbauer spectrometers, XRD installations, complex gas mixing station for electrical measurements under controlled gas atmosphere for gas sensing, specialized equipments for hydrothermal and co-precipitation synthesis.
A new atomic resolution TEM has been installed in 2011. The instrument is provided with probe Cs corrector of the spherical aberration, EDS and EELS microanalytical facilities. Another newly acquired equipment is the analytical SEM-FIB dual system which has been installed in a cleanroom next to equipments for photolithography and nanolithography.

     The research activity of the scientists working in this laboratory is focused on the physical properties of advanced materials (structure, optical, electrical properties), resulting either as size effects (nanostructures, thin films) or by structural defect engineering. The scientific concerns are mainly directed towards the discovery, investigation and manipulation of physical properties at nanometric and atomic scale for the development and characterization of new materials (dielectrics, semiconductors, alloys, ceramics) to be used in various applications (semiconductor technology, gas sensing, radiation detectors, telecommunications).
