Effects of surface passivation on top-down ZnO nanowire transistors
Unpassivated and passivated ZnO nanowire transistor characteristics are compared. These are fabricated using conventional top-down methods. Remote plasma atomic layer deposition and anisotropic ICP etch methods are used. Unpassivated NWFET show VTH of 6.5V, on/off ratio of 106 and ?o of 31.4cm2/Vs. Passivated NWFET show VTH of ?10V, on/off ratio of 104 and ?o of 35.5cm2/Vs.
