Figure 6

Patterning of AgNW networks and breakdown characteristics of the hybrid pattern. (a) An optical microscope image of patterned AgNW networks as channel by using dry etching. Top inset of (a) A schematic diagram of a device layout with patterned AgNW networks as channel. Scale bar is 30 μm. SEM images of AgNW networks (b) unexposed and (c) exposed to oxygen plasma. Scale bars are 5 μm. (d) A magnified SEM image of disconnected AgNW networks after dry etching process. Scale bar is 500 nm. (e) Comparison of electrical conductance of the AgNWs before and after reactive ion etching. (f) An optical microscopic image of patterned graphene-AgNW hybrid films by using dry and wet etching process. Scale bar is 10 μm. (g) Optical images of patterned hybrid films with various channel length after electrical breakdown. Scale bars are 10 μm. (h) I-V characteristics of AgNWs, graphene, and their hybrid channels (channel width: 10 μm, length: 50 μm). The lower graph is the magnification of the upper graph.
