Dr. Marian Zamfirescu



Marian Zamfirescu graduated in Physics in 1998, at the University of Bucharest. As young researcher he started the scientific activity in the "National Institute for Lasers, Radiation and Plasma Physics" from Bucharest (NILPRP). Here the research activity was mainly directed to the physics of Solid-State Laser and their applications in nonlinear optics.

In 2003 he received the PhD in Physics of Materials at University Blaise Pascal from Clermont-Ferrand, France, in the framework of EU-RTN CLERMONT project. During the three years of doctoral studies the research activity has mainly dealt with the investigation of light-matter interaction in wide bandgap semiconductors and heterostructures. He studied the excitonic and polaritonic effects in quantum wells and multiquantum wells, optical superlatices and microcavities. He developed theoretical models and used numerical techniques for simulation of the spectrally resolved and time resolved optical response of quantum wells and nitride microcavities.

As Experienced Researcher at the Department of Physics in Florence he extend the area of activites to the optical characterization of semiconductor heterostructures (quantum dots, quantum well, quantum rings, nanocolumns, pillar microcavities) structures with applications for emitting light devices in the blue-UV spectral rage, or optical devices like "Single Photon Emitter". By ultrafast spectroscopy have been studied effects of the polarization field on the excitonic dynamic in nitride heterostructures.

During many work stages in different Research Institutes from France and Italy, he acquired a large scientific experiences in the field of nanostructure characterization, including time-resolved spectroscopy, confocal microscopy, atomic force microscopy.

In present at NILPRP the scientific activity is focused on nanostructure growth and characterization using ultrafast laser pulses. He is involved in the development of an ultrafast laser facility for nanotechnology.
