... covered on SiNWs and not from the tip of SiNWs. High work function of the emitter makes electron emission difficult and reduces more the FE property of the emitter. Therefore, E on values of the Au/SiNWs ... properties of SiNWs were measured at the room temperature. The curves in Figure 2 display the emission current density (J) of SiNWs and Au/SiNWs as a function o...
