Cathodoluminescence Enhancement Mechanisms in Silica Microspheres
Hadar Aharon, Zahava Barkay, Sophie Meuret +1
Cathodoluminescence (CL) enables optical-frequency analysis of samples with nanometer resolutions, originating from the interaction of a focused electron beam with radiative electr…
Light's symmetry, asymmetry, and their role in nonlinear optics and ultrafast phenomena
Ofer Neufeld, Matan Even Tzur, Ofer Kfir +2
The analysis of symmetries is extremely useful across science. In Physics, symmetries are used to derive conservation laws and selection rules for transitions in interacting system…
Implementing strong interference in ultrathin film top absorbers for tandem solar cells
Yifat Piekner, Hen Dotan, Anton Tsyganok +4
Strong interference in ultrathin film semiconductor absorbers on metallic back reflectors has been shown to enhance the light harvesting efficiency of solar cell materials. However…
Chiral high-harmonic generation and spectroscopy on solid surfaces using polarization-tailored strong fields
Tobias Heinrich, Marco Taucer, Ofer Kfir +4
Strong-field methods in solids enable new strategies for ultrafast nonlinear spectroscopy and provide all-optical insights into the electronic properties of condensed matter in rec…
Probing chirality with inelastic electron-light scattering
Tyler R. Harvey, Jan-Wilke Henke, Ofer Kfir +4
Circular dichroism spectroscopy is an essential technique for understanding molecular structure and magnetic materials, but spatial resolution is limited by the wavelength of light…
Controlling free electrons with optical whispering-gallery modes
Ofer Kfir, Hugo Lourenço-Martins, Gero Storeck +5
Free-electron beams serve as uniquely versatile probes of microscopic structure and composition, and have repeatedly revolutionized atomic-scale imaging, from solid-state physics t…
