Spin Filtering

The transport properties of transition metal atoms interfered alpha-graphyne nanoribbon systems are investigated by first-principles calculations combined with the Keldysh nonequilibrium Green’s method. In all, five types of configurations are considered. We find that intervention of three Cr atom in alpha-graphyne nanoribbon systems decreases the conductivity of the system. Further study show that the magnetic direction of the electrode infulence the spin filtering effect greatly, while the ralative magnetic direction of the three transition Cr atoms have little effect on the transport properties. At finite bias window, negative differential resistance happens. Proper analysis are given to explain the spin filtering phenonmenon and the different transport properties via transmission coefficient and projected density of states.
