Electron Energy Loss Spectroscopy of 2D Materials in a Scanning Electron Microscope
John W. Simonaitis, Joseph A. Alongi, Benjamin Slayton +3
This work demonstrates electron energy loss spectroscopy of 2D materials in a 1-30 keV electron microscope, observing 100-times stronger electron-matter coupling relative to 125 ke…
Analysis and Applications of a Heralded Electron Source
Stewart A. Koppell, John W. Simonaitis, Maurice A. R. Krielaart +3
We analytically describe the noise properties of a heralded electron source made from a standard electron gun, a weak photonic coupler, a single photon counter, and an electron ene…
On-chip sampling of optical fields with attosecond resolution
Mina R. Bionta, Felix Ritzkowsky, Marco Turchetti +6
Time-domain sampling of arbitrary electric fields with sub-cycle resolution enables a complete time-frequency analysis of a system's response to electromagnetic illumination. This…
Light Phase Detection with On-Chip Petahertz Electronic Networks
Yujia Yang, Marco Turchetti, Praful Vasireddy +6
Ultrafast light-matter interactions lead to optical-field-driven photocurrents with an attosecond-level temporal response. These photocurrents can be used to detect the carrier-env…
Antiresonance-Like Behavior in Carrier-Envelope-Phase-Sensitive Optical-Field Photoemission from Plasmonic Nanoantennas
P. D. Keathley, W. P. Putnam, P. Vasireddy +4
Given the quasi-static nature of optical-field emission and the nontrivial dependence of the emission rate on the instantaneous electric field strength, the CEP-sensitive component…
Examining the Transition from Multiphoton to Optical-Field Photoemission From Silicon Nanostructures
Phillip D. Keathley, William P. Putnam, Guillaume Laurent +2
We perform a detailed experimental and theoretical study of the transition from multiphoton to optical-field photoemission from n-doped, single-crystal silicon nanotips. Around thi…
