Following the discovery of graphene, a large family of layered crystals has attracted significant attention. The properties of these materials range from superconductors and metals, to semiconductors and insulators. Properties of such quantum materials in a few-atomic-layer form are strongly influenced by the quantum confinement of the electronic excitations due to the extreme crystal thinness. Surprisingly, a family of layered ferromagnetic materials exists, which preserve their ferromagnetic properties even in an atomic monolayer form. Such 2D materials will revolutionise electronics, memory devices, and will have broad applications in quantum technologies, particularly in combination with other layered semiconductors. In this PhD project you will discover novel ferromagnetic monolayer materials, work on advancing their fabrication, and will develop methods for combining such materials with other 2D monolayer crystals such as graphene and transition metal dichalcogenides (TMDs). The goal is to fabricate and explore novel types of opto-electronic devices taking advantage of very large local magnetic field generated by 2D ferromagnetic materials on the nano-scale.
You will join an energetic team of 4 PhD students and 3 postdocs. You will work on novel device fabrication in the modern clean room, and will carry out a large number of optical experiments in the state-of-the-art laboratories of the Sheffield group. You will further collaborate with leading groups around the world on physics and technology of 2D materials and nano-photonics. We work closely with the leading groups in many related research fields, including 2D materials (National Graphene Institute, Manchester), nano-photonics and materials (Imperial College London), and optical spectroscopy (Technical University Dortmund) and many others, and visits to their experimental facilities will be possible and encouraged.
