Magnetism or no magnetism? The influence of substrates on electronic interactions

Nanowerk  November 9, 2022 While technological developments of 2D MOFs typically take advantage of substrates for growth, support, and electrical contacts, investigations often ignore substrates and their dramatic influence on electronic properties. Researchers in Australia have shown how substrates alter the correlated magnetic phases in Kagome MOFs using systematic density functional theory and mean-field Hubbard calculations. They demonstrated that MOF-substrate coupling, MOF-substrate charge transfer, strain, and external electric fields are key variables, activating and deactivating magnetic phases in these materials. They used the Kagome-arranged 9,10-dicyanoanthracene molecules coordinated with copper atoms as an example. According to the researchers their findings can […]
