Abstract
The electronic and transport properties in an antiferromagnetic junction of edge functionalized stanene nanoribbons (SnNRs) were studied using first-principle density functional theory. The behaviour of quantum conductance at zero bias voltage with varying ribbon widths in bare and edge hydrogenated SnNRs is demonstrated. The conductance gap near the Fermi level decreases with increasing the width of edge hydrogenated and pristine zigzag and armchair SnNRs. Moreover, the number of conductance channels also increases with increasing the ribbon width. The observed density of states (DOS) are completely corroborating the conductance profile in all the SnNRs. The conductance profile in all zigzag SnNRs exhibits a semiconducting behaviour in antiferromagnetic configuration. In contrast to other armchair SnNRs, 3n+2 armchair SnNRs exhibit a conducting behaviour, which shows the metallic property of corresponding SnNRs. These predictions indicating that stanene nanoribbons of appropriate width could be useful for spintronic applications.
