2DMS – Two dimensional magnetic semiconductors

Summary

The original goal of this project was dual. First, to explore the synthesis of a new class of 2D materials that are at the same time semiconductors and ferromagnetic, by doping a well-known class of 2D semiconductors, transition metal dichalcogenides, with magnetic atoms such as Fe. Second, to anticipate the magneto-optical properties of this class of compounds, paying attention to the challenging problem of probing magnetism in 2D Materials.

The overarching long-term goal of this research line was to explore ferromagnetic 2D materials that could be integrated into vertical stacks with other 2D materials to produce functional devices, such as spintronic devices.

In the short run, the impact belongs to the fundamental research area. Given the very high interest of this field of magnetic 2D materials, the project has already led to publications in journals with high visibility (Science, Nano Letters, Andgewandte Chemie, 2D Materials). In the long run, the results of the project could set the foundations of a new class of functional materials. In order to maximise the impact of the project, the INL and UT partners at the time of data collection for this report were writing a review paper on the state-of-the-art of the emerging field of 2D diluted magnetic semiconductors.
