| Abstract Scope |
Self-assembly has large untapped potential to create complex materials with nanoscale architectures that are not readily available by top-down fabrication processes. The self-organization of these materials is determined by fascinating far-from-equilibrium reaction-transport phenomena. Here, we exploit self-organization of copper-vanadium plasmonic networks in a reaction–diffusion system based on chemical dealloying. Taking advantage of the immiscibility of copper and vanadium, we leverage this non-equilibrium process to create optical metamaterials with complex connected architectures. By tuning the electrochemical potential, we demonstrate tunability of the oxidation state of the vanadium-rich phase. Through the combination of Rutherford backscattering spectroscopy (RBS), focused ion beam (FIB) tomography and optical spectroscopy, we analyze the dynamics of pattern formation and showcase the potential of these systems as energy materials. |
