Senior Researcher in Group of Nanomaterials and Nanostructures based on SiGeSn, Atomic Structures and Defects in Advanced Materials Laboratory, National Institute of Materials Physics
Associate Professor at University of Bucharest, Romania
Corresponding member of the Academy of Romanian Scientists
Professor Ciurea has important contributions in the field of group IV Si-Ge-Sn and ferroelectric HfO2 nanomaterials and nanostructures with applications in optoelectronics, photonics and nanoelectronics, deposited by magnetron sputtering and nanostructured either in situ during growth and/or ex situ by (rapid thermal, furnace) annealing. Research focused on: formation of group IV quantum dots embedded in dielectrics, with controlled size and adjustable density; preparation of CMOS compatible high-k oxide matrices and gate oxides; ferroelectric orthorhombic phase HfO2 formation and stabilization by HfO2 capping and self-controlled Ge doping assisted by strain deformation; electrical, charge storage, ferroelectric and photoelectrical properties; nanoscale phenomena; size effects; group IV photonics; VIS-SWIR photodetectors and optical sensors; nonvolatile (photonic) memory devices; nanoscale strain in nanostructures and devices.
She established SiGeSn Group in NIMP and led it for more than 25 years. She was also head of “Low Dimensional Systems” Laboratory in NIMP, and Scientific Director of R&D Programs MATNANTECH and CEEX from Romanian National Plans PN I & II.
Her research activity is reflected by more than 120 ISI scientific publications, 3 patents, 7 patent applications, 8 book chapters and more than 30 plenary and invited lectures at international conferences and prestigious EU & USA universities/ institutes.
