The best of both worlds: electrically detected optical spectroscopy at the single atom limit. One atom, one photon, one electron, in a silicon crystal. We will demonstrate a novel technique to detect the absorption of light by a single atom, in the most significant environment for nanoelectronics and photovoltaics. Our technique will help unravel how light is turned into electricity at the most microscopic and fundamental level.
