We employ near-infrared single-cycle pulse pairs to drive interferometric autocorrelations of the ultrafast current produced by optical field emission at the nanogap of a single plasmonic nanocircuit. This highly nonlinear process depends fully on the precise temporal field profile of the optical driving pulse. Current autocorrelations are acquired with sub-femtosecond temporal resolution as a function of both pulse delay and absolute carrierenvelope phase. In this way, we study the ultrafast dynamics of electronic nanotransport. Quantitative Additional information
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
