Schematic of InAs lattice (IMAGE) University of California - Los Angeles Caption Schematic of InAs lattice in contact with a nanoantenna array that bends incoming light so it is tightly confined around the shallow surface of the semiconductor. The giant electric field created across the surface of the semiconductor accelerates photo-excited electrons, which then unload the extra energy they gained by radiating it at different optical wavelengths.
