Abstract

Nonlinear photoemission from single nanostructures is investigated over a broad wavelength range in the near- and mid-infrared. The field enhancement at a nanotip apex and mid-infrared excitation enable sub-cycle dynamics, where electrons are ejected from the near-field within a fraction of the optical half-cycle. The implications of this field-driven acceleration are studied via photoemission spectrocopy and numerical simulations.
