Photoacoustic ultrasound sources from diffusion-limited aggregates
, 2016 Metallic diffusion-limited aggregate (DLA) films are well-known to exhibit near-perfect broadband optical absorption. We demonstrate that such films also manifest a substantial and relatively material-independent photoacoustic response, as a consequence ...
