Textured network devices are proposed as a solution to the fundamental problems of nanotube/nanowire network-based devices (see image). Significantly, both experiment and simulation show that “textured” network channels have enhanced mobility and conductivity with reduced channel width, which makes this strategy ideal for nanoscale device applications.
