FIG. 1.

(a) Top view SEM image of the as-grown honeycomb structure CNT mesh, while (b) shows the image at 45° tilt. (c) Cross sectional SEM image of the VACM array showing uniform, high density, and vertically aligned CNTs. (d) TEM image of multiwall CNTs with a diameter range of 5–15 nm. (e) SEM image of CNT forest, the inset shows the zoom in image. (f) Simulation results of the electric field distribution along “edges” of the honeycomb-shaped VACM array.
