Researchers at Rice University and Los Alamos National Laboratory found halide perovskite semiconductors (silver) treated with a thin layer of cesium (blue-green) could be tuned to emit free electrons (gray) over both the visible and ultraviolet spectrum (colored arrows), and that a fresh layer of cesium could regenerate degraded photocathodes.
