A new two-dimensional metal-organic framework with high spin-filtering efficiency.

Here we propose a family of two-dimensional organometallic lattices based on first principle calculations. The proposed lattice is designed by assembling molecular building blocks of a naphthalene molecule functionalized by -NH groups and transition metals which are surrounded by four -NH moieties, creating a square planar geometry. The predicted organometallic lattices (with Fe, Cr and Co) are shown to exhibit half metallicity and therefore this class of materials has great promise for application of spintronics.
