Expertise

My scientific and technical expertise covers the following domains: materials science and engineering, Molecular Beam Epitaxy, Chemical Vaport Deposition, nanofabrication for quantum technologies, semiconductor and cleanroom fabrication, compound semiconductors, Nanowires Nanotechnology, Solar Cell fabrication and characterization, Raman and luminescence spectroscopy

Mission

In the last two decades, our research activities have focused on the materials science and engineering of semiconductor materials, targeting applications in next-generation quantum and photoconversion technologies. We are dedicated to exploring how nanoscale materials can provide enhanced or novel properties, while also investigating how innovative nanoprocessing techniques can facilitate the fabrication of new materials. A key aspect of our work is to enhance the sustainability of semiconductors, either by minimizing the quantities required or by developing semiconductors composed of abundant earth elements.
