title: Sub-5 nm nanobowl gaps electrochemically templated by SiO2-coated Au nanoparticles as surface-enhanced Raman scattering hot spots.
abstract: Large-area submonolayer and monolayer Au nanoparticle (NP) arrays with sub-5 nm nanobowl gaps for giant electromagnetic enhancement were created by partially embedding SiO2-coated Au NP arrays in an electrochemically deposited Au film, followed by the removal of the SiO2 shells.
