Figure 8. — 3D architectures made of aligned SWCNT films. (a) Nematic order parameter (S, left axis) and the extinction ratio (ER, right axis), as a function of film thickness. (b) 1-inch and 2-inch aligned films made using controlled vacuum filtration. (c) A multilayer structure by stacking thin films of aligned SWCNTs and sandwiching doping molecules in-between. (d) Height profile of stacked films from one layer to four layers. (e) ER versus frequency in the THz range for 1–4 layers. (f) ER versus frequency in the THz range before and after doping. (g) ER versus frequency in the infrared range before and after doping. Adapted from [66,76].
