Two-dimensional (2D) van der Waals materials are a promising class of materials due to their exotic properties, reduced dimension, and ability to be combined in layered heterostructures. Such heterostructures are candidates for spintronics applications provided suitable magnetic materials are identified. Monolayers of transition-metal dichlorides (MCl2) are predicted to feature ferromagnetism. To date, however, only FeCl2 has been experimentally realised.
This project aims to grow MCl2 monolayers with M = Fe, Ni, and Co using a molecular beam epitaxy (MBE) method, and then to characterise their structural, electronic, and magnetic properties via scanning probe microscopy (SPM).
This project also aims to investigate interactions between MCl2 and other magnetic materials to understand their influence on spintronics. Magnetic metal-organic materials will be grown upon MCl2 monolayers using MBE and characterised using SPM to assess the influence of MCl2 on the adsorbed materials.
This project marks a step towards efficient spintronics technologies.
