Single photon emitters in hBN: Limitations of atomic resolution imaging and potential sources of error
David Lamprecht, Shrirang Chokappa, Alissa M. Freilinger +9
There is a growing interest in identifying the origin of single-photon emission in hexagonal boron nitride (hBN), with proposed candidates including boron and nitrogen vacancies as…
Plasmon-interband hybridization and anomalous production of hot electrons in aluminum nanoantennas
Jérôme Martin, Oscar Avalos-Ovando, Thomas Simon +9
Strong coupling typically occurs between two separate objects or between an object and its environment (such as an atom and a cavity). However, it can also occur between two differ…
Optical absorption in hexagonal-diamond Si and Ge nanowires: insights from STEM-EELS experiments and ab initio theory
Luiz H. G. Tizei, Michele Re Fiorentin, Thomas Dursap +6
Hexagonal-diamond (2H) group IV nanowires are key for advancing group IV-based lasers, quantum electronics, and photonics. Understanding their dielectric response is crucial for pe…
Roadmap for Quantum Nanophotonics with Free Electrons
F. Javier GarcÃa de Abajo, Albert Polman, Cruz I. Velasco +44
Over the past century, continuous advancements in electron microscopy have enabled the synthesis, control, and characterization of high-quality free-electron beams. These probes ca…
Direct measurement of the longitudinal exciton dispersion in hBN by resonant inelastic x-ray scattering
Alessandro Nicolaou, Kari Ruotsalainen, Laura Susana +7
We report resonant inelastic X-ray scattering (RIXS) measurements on the prototypical hexagonal boron nitride hBN layered compound. The RIXS results at the B and N K edges have bee…
