My current research focuses on the investigation of material dynamics under extreme conditions, particularly pressure and temperature, to explore the unique properties of quantum materials. By applying pressure, I aim to fine-tune the ground state of these systems, potentially inducing phase transitions and enabling precise control of their properties. This allows for the study of their dynamic response to ultrashort light pulses. I use advanced techniques such as synchrotron-based X-ray spectroscopy, Raman, THz spectroscopy, and scattering methods to analyze nanomaterials like thin films, nanowires, and nanoparticles. My work spans the complex phase diagrams of quantum materials, offering insight into their behavior and transitions under varying conditions.
I obtained my BSc in Physics and my MSc in Materials Physics and Technology from the Aristotle University of Thessaloniki, in Greece, in 2020 and 2023 respectively. As a part of my Senior Thesis I was involved in the development and complete characterization of Organic LEDs made of anthracene polymeric thin films at the LTFN Nanotechnology Laboratory in Thessaloniki. In my Master, I was mainly interested in the optical and nanostructural properties of materials and that’s the reason I chose as a thesis topic the investigation of the growth process of GaN nanowires from the nitridation of β-Ga2O3 nanowires by Raman spectroscopy and Synchrotron radiation techniques (SAXS, EXAFS, XRF). In particular, I developed an innovative methodology to determine their filling factor by combining information from each one of the techniques applied.
