Oxide electronics: Zinc oxide nanostructured LEDs and tantalum oxide nonvolatile memories

By Eileen De Guire / July 18, 2011

Zinc oxide nanostructures are synthesized in parallel microfluidic channels (held by the metal frame) by flowing reactants through the tubing. The microfluidic structure creates the device and also becomes the final packaged functional LED device.

Speaking of ZnO nanowires, chemists at NIST who were perfecting new methods of creating these nanowire report that they have stumbled upon a way to create light-emitting nanowires that operate like very tiny LEDs. The chemists, Babak Nikoobakht…
