Title
Engineering Synthetic 2D Magnetic Materials for Energy-Efficient Computing

ABSTRACT: The discovery of long-range magnetic order in atomically thin two-dimensional (2D) materials is a new emerging field promising for future applications in ultra-compact low-power spintronics, miniaturized memory technologies, neuromorphic computing etc. The family of 2D magnets is rapidly expanding and the van der Waals and non-van der Waals chalcogenides of chromium are emerging as air stable magnetic materials with magnetism at room temperatures. In this talk, I will present our work on the MOCVD (metal organic chemical vapour deposition) of different crystal phases of chromium di-chalcogenides atomically thin crystals deposited onto different epitaxial substrates. The synthesis precision, represented by the phase selectivity, is achieved by the combination of the kinetic control of the synthesis and the chemistry of the chosen precursors. We demonstrate that different polymorphs exhibit distinct magnetic properties suitable for future integration in ultra-thin memory devices.
