Abstract

The structural stability, spin-polarized electronic and transport properties of edge-hydrogenated zigzag boron nitride nanoribbons (ZBNNRs) are investigated using density functional theory (DFT) combined with a non-equilibrium Green's function (NEGF) approach. The considered structures are observed to be energetically stable in the magnetic ground state. The calculated spin-dependent transport properties indicate that a selective-edge hydrogenated ZBNNR device shows bipolar spin filter characteristics. Interestingly, high spin giant magnetoresistance (GMR) and a rectification ratio (RR) are observed of the order of 1015 and 1010, respectively. The observed GMR and rectification behavior in edge-hydrogenated ZBNNRs have potential applications for designing future spintronic nanodevices.
