Refractory doped titanium nitride nanoscale field emitters
Alberto Nardi, Marco Turchetti, Wesley A. Britton +5
Refractory materials exhibit high damage tolerance, which is attractive for the creation of nanoscale field-emission electronics and optoelectronics applications that require opera…
Impact of DC bias on Weak Optical-Field-Driven Electron Emission in Nano-Vacuum-Gap Detectors
Marco Turchetti, Mina R. Bionta, Yujia Yang +5
In this work, we investigate multiphoton and optical-field tunneling emission from metallic surfaces with nanoscale vacuum gaps. Using time-dependent Schrodinger equation (TDSE) si…
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…
Electron-Energy Loss of Ultraviolet Plasmonic Modes in Aluminum Nanodisks
Yujia Yang, Richard G. Hobbs, Phillip D. Keathley +1
We theoretically investigated electron energy loss spectroscopy (EELS) of ultraviolet surface plasmon modes in aluminum nanodisks. Using full-wave simulations, we studied the impac…
Nanostructured-membrane electron phase plates
Yujia Yang, Chung-Soo Kim, Richard G. Hobbs +2
Electron beams can acquire designed phase modulations by passing through nanostructured material phase plates. These phase modulations enable electron wavefront shaping and benefit…
