#MATERIALS: "Quantum dots enable plasmonic semiconductors"

Plasmonic semiconductors could revolutionize electronics by coupling photons and electrons into synchronized wavefronts that travel in waves on a chip's surface. These surface plasmon resonances enable electronic interconnect where the signals travel at the speed of light, on-chip lenses for lasers and a new generation of super-efficient plasmonic light-emitting diodes (LEDs), supersensitive chemical and biological detectors, and metamaterials that can bend light around objects to create an invisibility cloak.
