High quality metal thin films and nanostructures are critical building blocksfor next generation nanotechnologies. They comprise low-loss circuit elementsin nanodevices, provide new catalytic pathways for water splitting and $CO_2$reduction technologies, and enable the confinement of spatially extendedelectromagnetic waves to be harnessed for application in informationprocessing, energy harvesting, engineered metamaterials, and new technologiesthat will operate in the quantum plasmonics limit. However, the controlledfabrication of high-definition single-crystal subwavelength metalnanostructures remains a significant hurdle, due to the tendency forpolycrystalline metal growth using conventional physical vapor depositionmethods, and the challenges associated with placing solution-grown nanocrystalsin desired orientations and locations on a surface to fabricate functionaldevices. Here, we introduce a new scalable, green, wet chemical approach tomonocrystalline noble metals that enables the fabrication of ultrasmooth,epitaxial, single-crystal films of controllable thickness. They are ideal forthe subtractive manufacture of nanostructure through ion beam milling, andadditive crystalline nanostructure via lithographic patterning to enable largearea, single-crystal metamaterials and high aspect ratio nanowires. Oursingle-crystal nanostructures demonstrate improved feature quality and patterntransfer yield, reduced optical and resistive losses, tailored local fields,and greatly improved stability compared to polycrystalline structures,supporting greater local field enhancements and enabling new practical advancesat the nanoscale.
