Robust negative differential resistance and abnormal magnetoresistance effects in heteroatom-substituted zigzag γ-graphyne nanoribbon homojunctions

By using O atoms to substitute H atoms while B or N atoms to substitute edge C atoms to obtain chemically modified ZγGYNRs, then coupling two ZγGYNRs by the interface to build corresponding homojunctions, the transport properties of spintronic devices can be dramatically enhanced.
