Carbon Nanotubes making Holograms

Researchers from the University of Cambridge's Department of Engineering have demonstrated the novel utilisation of carbon nanotubes for making high resolution holograms.

Carbon nanotubes - a manmade material - have been the focus of an enormous amount of research during the last decade due to their extraordinary electrical and optical properties. These tubes are many times thinner than a wavelength of visible light which makes them promising candidates for being used as pixels.
