A series of articles produced by a team at the Physical Electronics and Nanotechnology Group located in Campus Norrköping of Linköping University (Linköping, Sweden) reports on interesting and unusual developments related to the growth of LEDs on paper substrates. With this as a research topic, one can start to imagine ahead a few years to a successful commercialization of the technology. Beyond flexible displays, think about a glowing curtain blowing in the breeze or luminous wallpaper.
The work reported in this article is, in part, drawn from the doctoral thesis of recent graduate Gul Amin. It is entitled "ZnO and CuO Nanostructures: Low Temperature Growth, Characterization, their Optoelectronic and Sensing Applications" and can be found here. This site also includes a list with links to all the papers on this subject that were products of his graduate work.
