  • Publication number: 20160377549
    Abstract: By forming a monolayer of metal core-shell nanoparticles, transferring the monolayer to various substrates and removing the shells surrounding the particles by way of selective etching, it is possible to form large-area uniform nanogap structures very easily. In addition, a nanogap is formed by an ultrasmall void having no limitation in diffusion between metal cores through Van der Waals interaction between the metal core particles, as the etching proceeds. It is possible to enhance a near-field significantly around the nanogap structure.
