UV Photodetectors In article number 2402558, Jeff Huang, Noushin Nasiri, and co-workers feature a 3D-rendered set of interdigitated electrodes with an abstracted porous nanoparticle film, the architecture of the UV photodetectors in their study. Incident UV light is converted into an electrical current, shown as lightning bolts on the particles. The inset circle highlights vapor-tailoring of nanoparticle interfaces, with droplets condensing at the particle boundaries to enhance charge carrier transport.
