In this research line, we explore the electronic structure and functional properties of semiconductors doped with magnetic impurities, known as diluted magnetic semiconductors (DMS). By combining advanced microscopy techniques with spectroscopic and resonant methods, we seek to understand how magnetic dopants influence carrier behavior, magnetic coupling, and defect-mediated phenomena at the nanoscale.
Our experimental approach integrates high-resolution electron microscopy, scanning tunneling microscopy (STM)under ultra-high vacuum, paramagnetic electron resonance (EPR), and X-ray photoelectron spectroscopy (XPS) to correlate atomic-scale structure with magnetic and electronic responses. Through this multi-scale characterization, we aim to elucidate the origins of ferromagnetism in DMS systems and the role of intrinsic and extrinsic defects in governing their behaviour.
Building on these fundamental insights, we are developing prototype spintronic devices, such as spin-photodiodes and spin-valves, that leverage spin-dependent transport and magnetic phenomena. These devices represent key steps toward next-generation data storage and processing technologies, where control of electron spin offers new paradigms in performance, efficiency, and integration.
