A breakthrough could make infra-red technology easy-to-use and cheap, potentially saving millions of dollars in defense and other areas using sensing devices for night vision, and boosting applications to a host of new areas, including agriculture. Researchers have demonstrated a dramatic increase in the absorption efficiency of light in a layer of semiconductor only a few hundred atoms thick -- from 7.7 percent currently to almost 99 percent light absorption.
