Nanoantenna Design for Enhanced Carrier-Envelope-Phase Sensitivity
Drew Buckley, Yujia Yang, Yugu Yang-Keathley +2
Optical-field emission from nanostructured solids such as subwavelength nanoantennas can be leveraged to create sub-femtosecond, PHz-scale electronics for optical-field detection.…
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…
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…
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…
