Researcher Spotlight: Atom­Thick Material Offers 2D Imaging Possibilities

Rice University scientists have developed a two-­dimensional, atom­-thick, light-­sensitive material called CIS, a single­-layer matrix of copper, indium, and selenium atoms. Sidong Lei, a graduate student, also built a prototype — a three-­pixel charge­-coupled device (CCD) sensor — to prove the material’s ability to capture an image. The optoelectronic memory material may be the basis for future flat imaging devices and two­-dimensional electronics.
