The dataset "Self-Organized Nanoplasmonic Artificial Leaf for Hot-Carrier Bioelectronic Interfaces" consists of raw data files for Main Figures 1 through 5, stored in compressed ZIP archives, along with a code repository and supplementary information. The data supports research on nanoplasmonic artificial leaf structures designed for hot-carrier bioelectronic interface applications. The project was created on May 11, 2026, and last updated on June 16, 2026, with contributions from Pengju Li.
