Super-resolution imaging of nanoscale inhomogeneities in hBN-covered and encapsulated few-layer graphene
Lina Jäckering, Konstantin G. Wirth, Lukas Conrads +9
Encapsulating few-layer graphene (FLG) in hexagonal boron nitride (hBN) can cause nanoscale inhomogeneities in the FLG, including changes in stacking domains and topographic defect…
Improved Three-Dimensional Reconstructions in Electron Ptychography through Defocus Series Measurements
Marcel Schloz, Thomas C. Pekin, Hamish G. Brown +9
A detailed analysis of ptychography for 3D phase reconstructions of thick specimens is performed. We introduce multi-focus ptychography, which incorporates a 4D-STEM defocus series…
Metasurface of strongly coupled excitons and nanoplasmonic arrays
Farsane Tabataba-Vakili, Lukas Krelle, Lukas Husel +6
Metasurfaces allow to manipulate light at the nanoscale. Integrating metasurfaces with transition metal dichalcogenide monolayers provides additional functionality to ultrathin opt…
Interplay of plasmonics and strain for Hexagonal Boron Nitride emission engineering
Anuj Kumar Singh, Utkarsh, Pablo Tieben +11
In the realm of quantum information and sensing, there has been substantial interest in the single-photon emission associated with defects in hexagonal boron nitride (hBN). With th…
