Michael Shentcis,Adam K. Budniak,Raphael Dahan,Yaniv Kurman,Xihang Shi,Michael Kalina,Hanan Herzig Sheinfux,Mark Blei,Mark Kamper Svendsen,Yaron Amouyal,Frank H. L. Koppens,Sefaattin Tongay,Kristian Sommer Thygesen,Efrat Lifshitz,Javier García de Abajo,Liang Jie Wong,Ido Kaminer +16 more
TL;DR: In this article, the first observation of energy-tunable X-ray radiation from van-der-Waals materials is presented, which is achieved by control of the incident electron energy and lattice structure.
Journal ArticleDOI
SERS Platforms of Plasmonic Hydrophobic Surfaces for Analyte Concentration: Hierarchically Assembled Gold Nanorods on Anodized Aluminum
Moritz Tebbe,Pavel V. Cherepanov,Ekaterina V. Skorb,Sergey K. Poznyak,Javier García de Abajo,Andreas Fery,Daria V. Andreeva,Ramon A. Alvarez Puebla,Nicolas Pazos-Perez +8 more
TL;DR: In this paper, a method for designing low-cost, up-scalable surface patterns that match building block dimensionality based on anodization of aluminum, enabling a hierarchical organization of anisotropic nanoparticles, is presented.
Proceedings ArticleDOI
Demonstration of Near-field THz Spectroscopy Using Ultrafast Electron Microscopy
Michael Yannai,Raphael Dahan,Alexey Gorlach,Nicholas Rivera,Kangpeng Wang,Giovanni Maria Vanacore,Fabrizio Carbone,Javier García de Abajo,Ido Kaminer +8 more
TL;DR: In this article, near-field THz pulses with nm-fs spatio-temporal resolution were investigated through their interaction with free-electron pulses in an ultrafast transmission electron microscope.
Proceedings ArticleDOI
Free-Electron Interactions with Designed van der Waals Materials: Novel Source of Lensed X-ray Radiation
TL;DR: In this paper, free electron interactions with van der Waals materials are used to create intrinsic lensing of the generated X-rays, where the crystal geometry is shaped to create the intrinsic lens.
Proceedings ArticleDOI
Spectrometer-free electron probe of ultrafast thermal dynamics in optically excited samples
TL;DR: In this paper, the plasmon excitation dynamics in nanostructured graphene and graphite can be traced through energy integrated and momentum resolved spectra of inelastically scattered electrons in contrast to more traditional energy-resolved spectroscopy approach.
