Abstract

In our project we will focus on the subtle magnetic interactions between 2D metal-organic frameworks, so-called MOFenes, and various graphene systems (graphene and gated Bernal-stacked bilayer graphene, gBLG). These frameworks contain metal centers as nodal elements connected by organic ligands, and the metal centers carry charge and/or spin centers. MOFenes with a characteristic lattice thus will impose a charge/magnetic superlattice of the same structure on any interfaced 2D material, such as graphene or gBLG. In such heterostuctures (HSs) we will be able to investigate effects of lattice topology and different metal centers on the resulting magnetism of the HS.

We will use a range of experimental and theoretical methods, including advanced material transfer techniques, quantum transport, scanning near-field microscopy, nanoscale scanning spectroscopy, orthogonal tight-binding hamiltonians, density-functional theory (DFT), DFT based tight-binding, and quasiparticle methods.
