Momentum microscopy of a holey nanostructure
Kerstin Harland, Julia Altenburg, Xiaofei Wu +10
Momentum microscopy records the three-dimensional momentum distribution of photoelectrons emitted from a solid sample and, by utilizing sufficiently high photon energies in the ult…
Momentum microscopy of ultrafast electron emission from a strongly driven optical nanoantenna
Kerstin Harland, Germann Hergert, Zsuzsanna Pápa +9
Metallic nanostructures in combination with femtosecond lasers are a well-suited platform for the control of photoelectrons by strong and nano-localized driving fields, with high r…
Planar chiral nanoantenna for excitation-chirality-controlled hot spot modulation and emitter-coupled circularly polarized emission
Abhik Chakraborty, Xiaofei Wu, Ankit Kumar Singh +5
A planar chiral plasmonic nanoantenna exhibiting an excitation-chirality-dependent hot spot in a nanogap is numerically investigated. Additionally, the underlying design principles…
Crystalline metal flakes: Platforms for advanced plasmonics and hybrid 2D material architectures
Sergejs Boroviks, Siarhei Zavatski, Thorsten Feichtner +4
Crystalline noble metal flakes are emerging as versatile platforms in nanophotonics, enabling a broad range of optical phenomena and applications. Their atomically flat surfaces, h…
