Probe- and Substrate-Dependent Visibility of Mie Resonances in Silicon Nanospheres
Yonas Lebsir, Huatian Hu, P. A. D. Gonçalves +5
Silicon nanospheres are high-quality optical resonators and promising building blocks for Mie-tronic devices. While the Mie resonances of an isolated sphere are well understood, pr…
An atlas of photonic and plasmonic materials for cathodoluminescence microscopy
Sven Ebel, Yonas Lebsir, Torgom Yezekyan +2
Cathodoluminescence (CL) microscopy has emerged as a powerful tool for investigating the optical properties of materials at the nanoscale, offering unique insights into the behavio…
Ultimate limit for optical losses in gold, revealed by quantitative near-field microscopy
Yonas Lebsir, Sergejs Boroviks, Martin Thomaschewski +2
We report thorough measurements of surface plasmon polaritons (SPPs) running along nearly perfect air-gold interfaces formed by atomically flat surfaces of chemically synthesized g…
