Salem Marhaba

Associate Professor of Nano-Sciences


Salem Marhaba received his Ph.D. degree in Physics from University of Lyon I in 2008. After that, He was employed as a Non-Permanent Assistant Professor at the University of Pierre and Marie Curie (Paris VI) in 2009 and at the University of Littoral Cote d’Opale in 2010. He was an Assistant Professor in the Department of Physics at Beirut Arab University from February 2011 to July 2015. Currently, he is Associate Professor in the Department of Physics at Beirut Arab University since August 2015. He has already published more than fifteen publications in scientific reviews, as well as, he has presented some of his works in the international conferences. He has provided practical and theoretical work to make the connection between theory and experiments, which is fundamental in physics. Moreover, this allowed him not only to help students in difficulty but also to answer questions from curious students. He feels it is his responsibility to improve the knowledge of students and then encourage them to work up to their potential. In addition to classroom instructor, he has advised students on appropriate research topics. Throughout his career, he has acquired an important knowledge in the domain of nanotechnology. He has a solid experience in the far-field optical techniques. Also he has a good experience in the transmission electron microscopy (TEM) for characterization of nanoparticles. In addition to his responsibilities as a coordinator of Physics Department at Beirut Arab University, he continues his research on the optical response of metallic nanoparticles and the properties of superconductor materials.

Research

Research Interests

My research interests are in the area of optical properties of nanostructures, from a single nanoparticle to ensembles. In particular, the metallic nanoparticls (noble metal, especially Au) display potential for such applications as enhancing the fluorescence of biological molecules. The optical properties of noble metal nanoparticles are dominated by their surface plasmon resonance (SPR), which is known to closely depend on the size, shape and dielectric environment of the particle, and also on their chemical composition in the case of composite systems. In order to study the electronic and optical response of a single nanoparticle (or an isolated composite system, as a pair of particles) I used a high sensitive spectroscopic technique in far field: Spatial Modulation Spectroscopy (SMS). The SMS technique enables the absolute extinction cross-section of the nano-system to be determined on condition that the light spot profile in the focal region is known. We can deduce from the measured optical response the quantitative information on their size, shape and environment. For more information about these nanoparticles, I used the direct observation of the nanoparticles by Transmission Electron Microscopy (TEM). The coupling of SMS technique with TEM turns out to be essential to get an unambiguous description of their optical response in relation with their exact morphology. In addition, I’m interested in studying the linear optical response of 2D gold nanoparticle arrays using the spectrophotometer technique. During the last three years, my research has been mainly focused on studying the physical properties of superconductor materials by adding varieties of nanoparticles. Several types of techniques are required to obtain results as X-Ray powder Diffraction (XRD), Energy Dispersive X-ray emission (EDX), Proton Induced X-ray Emission (PIXE), Rutherford Backscattering Spectrometry (RBS) and Scanning Electron Microscopy (SEM).
