Correction to “The Electric Field Morphology of Plasmonic Picocavities”

In the original publication, in eqs S7 and S8 in the Supporting Information, the sign of the dipole contribution to the ωFQFμ induced electric potential and field is incorrect. The correct formula for the induced electric potential (eq S7 in the SI) at a generic point rj reads as follows: (formula presented) (a) ωFQFμ absorption cross sections σabs (nm2) and electric field enhancements (|E|/|E0|) calculated for the nanocavity (top) and picocavity (bottom), (b) Graphical depiction of nanocavity (top) and picocavity (bottom) induced density calculated at the plasmon resonance frequency (PRF), (c, d) 2D color map of nanocavity (top) and picocavity (bottom) induced density (c) and electric field enhancement (d) in a zoomed region in the middle yz plane (see green highlighted region in b panel).
