An Ultrafast Source of Attosecond Electron Pulses Triggered by a Surface Plasmon
View through CrossRef
We demonstrate a highly coherent ultrafast electron source based on plasmonic nanofocusing using a single groove at the shank of a nanotip. We find signatures of tunneling photoemission, indicating the emission of attosecond electron bursts.
