Rice, Sandia team uses carbon nanotubes for polarized-light detection
Using carpets of aligned carbon nanotubes, researchers from Rice University and Sandia National Laboratories have created a solid-state electronic device that is hardwired to detect polarized light across a broad swath of the visible and infrared spectrum.
The research is available online from the American Chemical Society’s journal ACS Nano.
“Detecting polarized light is extremely useful,” said Rice’s Junichiro Kono, professor of electrical and computer engineering and of physics and astronomy. “Many animals and insects can see polarized light and use it for navigation, communication and more. Humans can’t see polarized light, so we rely on devices to do that for us.” (...)
