I–V characteristics of ZnO nanoribbons (NRs) have been investigated using density functional theory coupled to non-equilibrium Green’s Function. The current through the NRs drops with the increasing NR width, leveling off to 1.66 and 0.42µA in zig-zag and arm-chair NRs respectively for widths ~20Å at 3V of electrical bias. The transconductance as well as the current flowing through the arm-chair NRs...
