Abstract
An electro-optical liquid crystal cell comprising a first substrate, a first layer of chromium (Cr), a first layer of vertically aligned carbon nanotubes (VA-CNT) capped with nickel nanoparticles, and a layer of liquid crystal. Furthermore, the electro-optical liquid crystal cell can comprise a second layer of VA-CNT capped with nickel nanoparticles, a second layer of Cr, and a second substrate. This electro-optic VA-CNT-based liquid crystal cell exhibits the required electro-optic effect needed for a liquid crystal display.
