Transient Optical Picocavities Within Coupled Plasmonic Nanostructures
… with transient features suggestive of possible picocavity formation. Picocavities are transient atomic scale features on the metal surfaces which further confine fields (effective volume <1 nm3) with strong field gradients that locally alter the rules for vibrational scattering efficiency. These …

Controlling and Understanding Atomic-Scale Dynamics within Plasmonic Nanogaps
… optical control over formation and stability of picocavity adatoms is first explored. Such control is achieved by pulses of visible light on an NPoM, where they rapidly write an adatom in the nanogap. The adatoms are shown to be storable in ambient conditions for up to a week in the dark and are …

Light and Single-molecule Coupling in Plasmonic Nanogaps
Plasmonic cavities confine optical fields at metal-dielectric interfaces via collective charge oscillations of free electrons within metals termed surface plasmon polaritons (SPPs). SPPs are confined in nanometre gaps formed between two metallic surfaces which creates an optical resonance. This …
