Caption

Optically excited hot electrons (red) move fast in a gold film, followed by a slower thermal diffusion as they cool (blue). This material relates to a paper that appeared in the date, issue of Science Advances, published by AAAS. The paper, by A. Block at The Barcelona Institute of Science and Technology in Barcelona, Spain, and colleagues was titled, "Tracking ultrafast hot-electron diffusion in space and time by ultrafast thermomodulation microscopy."
