Dr. Nikoletta Jegenyés is a research assistant at the Wigner Research Centre for Physics. She has obtained her doctorate degree at the University of Szeged in 2011. She then worked as a post-doctoral fellow in France (UCBL Lyon, École Polytechnique, Université d’Orsay), where her research topic was the growth and characterization of semiconductor nanostructures.
Her research interest is the elaboration of silicon-carbide nanocrystals and the creation of quantum bits in them. The structure and composition of the formed crystals are studied by electron microscopy (SEM), energy-dispersive X-ray elemental analysis (EDS) and atomic force microscopy (AFM). This is complemented by Raman spectroscopic and photoluminescence studies in order to obtain information on the polytype of crystals and to identify the induced point defects in nanostructures.
She participates in the realization of quantum optical measurements in the ODMR laboratory on individual artificial atoms created in nanoscale diamonds and silicon-carbide. She develops a modified confocal microscopic system based on ODMR phenomenon to measure quantum sensors.
