image: Colorized scanning electron micrograph of a representative nanoantenna array prior to ITO coating, taken with a 65° tilt angle. Device arrays consist of 20x15 individual Au resonators (shown in yellow), spaced by 250 nm center-to-center along both axes, and isolated from the underlying Si by a 30 nm thick layer of silica (blue). This image relates to an article that appeared in the May 6, 2011, issue of Science, published by AAAS. The study, by Mark Knight of Rice University in Houston, and colleagues, was titled, "Photodetection with Active Optical Antennas." view more
