ABOUT/BIOGRAPHY

Akylas Lintzeris is a physicist specializing in two-dimensional materials for spintronic and nanoelectronic applications. He obtained his Physics degree from the Department of Physics of the National and Kapodistrian University of Athens, where he subsequently completed an M.Sc. in Solid State Physics. He earned his Ph.D. from the School of Applied Mathematics and Physics of the National Technical University of Athens, in collaboration with the National Centre for Scientific Research “Demokritos”. His doctoral thesis, entitled “Epitaxial growth and properties of 2D ferromagnetic Cr₁₊δTe₂ for spintronic applications”, focused on the controlled synthesis and comprehensive investigation of emerging vdW magnetic materials.

His research activity is centered on the epitaxial growth, structural characterization, and magnetic properties of 2D ferromagnets, with particular emphasis on chromium telluride–based systems. His work aims to elucidate the interplay between crystal structure, stoichiometry, dimensionality, and magnetic anisotropy in ultrathin magnetic materials, targeting their integration into next-generation spintronic and nanoelectronic devices. A key aspect of his research is the development and optimization of MBE growth protocols for high-quality vdW magnetic thin films and heterostructures, enabling systematic studies of thickness-, substrate-, and strain-dependent magnetic behavior.

Dr. Lintzeris has conducted his doctoral and postdoctoral research at the Epitaxy and Surface Science Laboratory (ESSL) of the Institute of Nanoscience and Nanotechnology (INN), NCSR “Demokritos”, where he is currently a postdoctoral researcher. Within ESSL, he has gained extensive hands-on experience with advanced experimental techniques for the characterization of low-dimensional materials. His expertise includes in situ and ex situ structural characterization using RHEED, STM, XRD and XPS, as well as magnetic characterization using SQUID magnetometry and magneto-optical Kerr effect techniques.

He is particularly specialized in MOKE magnetometry and microscopy, which he has employed to investigate magnetic anisotropy, domain structure, coercivity, and magnetization reversal mechanisms in ultrathin ferromagnetic films. In addition, he has experience in electrical transport measurements, allowing the correlation of magnetic properties with charge transport behavior in 2D magnetic systems and heterostructures. Through these combined approaches, his work contributes to a deeper understanding of magnetic order and anisotropy stabilization in the two-dimensional limit.

Dr. Lintzeris actively participates in national and European research collaborations and has been involved in the HORIZON 2020 SKYTOP project, focusing on advanced material platforms for future electronic and spintronic technologies. His research interests broadly encompass vdW heterostructures, 2D ferromagnets, interface engineering, and the exploitation of magnetic and electronic functionalities in ultrathin materials. His long-term scientific goal is to contribute to the development of scalable 2D material-based devices for spintronic logic, memory, and low-power nanoelectronic applications.
