Ph.D student, Univ. Bucuresti, Fac. of Physics, Solid State Physics (Condensed Matter Physics) (1.XI.2001), prof. I. Licea
IFIN-HH Diploma nr45/2477 26.06.1988
CNCAN : Level 2 Licence for working with Nuclear Radiations nr. 148/2000
Professional experience: Optoelectronics, X-ray analysis methods
Profile analysis of X-ray spectra (polycrystals, bulk + thin films 10 Å-0.1mm):
phase composition (qualitative and quantitative)
grain size (1-3Å < Dhkl < 0.1mm);
structural changes (Dd/d >10-7);
texture (preffered nanocrystallite orientation)
crystalline fraction (for mixed amoprhous-crystalline phases).
Internall residual stress of first and second order;
Investigation of monocrystalline materials (including thin films):
elastic strain determination;
lattice misfit ant tetragonal distortion for heteroepitaxial layers;
monocrystalline wafer curvature determination;
damage distributions in monocrystalline structures (used in pressure sensors, micro and nano electro-opto-mechanical systems);
determination of crystallographic orientation of monocrystals
Computer tehniques used for X-ray spectra corrections and data extraction: texture, crystallinity, grain size, residual stress, first and second order tensions
The Nuclear Unit of IMT had also a set of specific software developed at Oak Ridge National Laboratory (sent by the author Camden R. Hubbard from ORNL, leader of Diffraction and Thermophysical Properties Group): XRAYL (a program for producing idealized powder diffraction line profiles from overlapped powder profiles) and CRYSIZ (a programm for computing crystallite size from the broadening of powder diffraction lines). In IMT, the program CRYSIZ is used to perform the modern Waren Averbach method of X-ray analysis of computing size and strain distributions, especially for the nanostructured materials.
