Generation and control of localized terahertz fields in photoemitted electron plasmas
Eduardo J. C. Dias, I. Madan, S. Gargiulo +6
Dense micron-sized electron plasmas, such as those generated upon irradiation of nanostructured metallic surfaces by intense femtosecond laser pulses, constitute a rich playground…
eV electron spectromicroscopy using free-space light
Yves Auad, Eduardo J. C. Dias, Marcel Tencé +7
The synergy between free electrons and light has recently been leveraged to reach an impressive degree of simultaneous spatial and spectral resolution, enabling applications in mic…
Ultrafast Electron Microscopy of Nanoscale Charge Dynamics in Semiconductors
Michael Yannai, Raphael Dahan, Alexey Gorlach +11
The ultrafast dynamics of charge carriers in solids plays a pivotal role in emerging optoelectronics, photonics, energy harvesting, and quantum technology applications. However, th…
Probing Nonlocal Effects in Metals with Graphene Plasmons
Eduardo J. C. Dias, David Alcaraz Iranzo, P. A. D. Gonçalves +6
In this paper we analyze the effects of nonlocality on the optical properties of a system consisting of a thin metallic film separated from a graphene sheet by a hexagonal boron ni…
Probing the Ultimate Plasmon Confinement Limits with a Van der Waals heterostructure
David Alcaraz Iranzo, Sebastien Nanot, Eduardo J. C. Dias +11
The ability to confine light into tiny spatial dimensions is important for applications such as microscopy, sensing and nanoscale lasers. While plasmons offer an appealing avenue t…
Controlling spoof plasmons in a metal grating using graphene surface plasmons
Eduardo J. C. Dias, N. M. R. Peres
Spoof plasmons mimic noble metal plasmons. The equivalent of the plasma frequency is an energy scale imposed by the geometry of the metal grating upon which they propagate. In this…
