2-D Material Shows Promise for Image Sensing
HOUSTON, Dec. 22, 2014 — Ultrathin chalcogenide films could form the basis of tiny, adaptable bioimagers. Composed of copper indium selenide (CIS), a prototype three-pixel CCD has already demonstrated the ability to capture and store image information, according to researchers at Rice University. Flexible CIS films could be curved to match the focal surface of an imaging lens system, which could allow for the real-time correction of optical aberrations, the researchers said. Rice University...
