Low-energy electron microscopy intensity-voltage data -- factorization, sparse sampling, and classification
Francesco Masia, Wolfgang Langbein, Simon Fischer +2
Low-energy electron microscopy (LEEM) taken as intensity-voltage (I-V) curves provides hyperspectral images of surfaces, which can be used to identify the surface type, but are dif…
Rydberg Excitons in Synthetic Cuprous Oxide (CuO)
Stephen A. Lynch, Chris Hodges, Soumen Mandal +8
High-lying Rydberg states of Mott-Wannier excitons are receiving considerable interest due to the possibility of adding long-range interactions to the physics of exciton-polaritons…
Polarization-resolved extinction and scattering cross-section of individual gold nanoparticles measured by wide-field microscopy on a large ensemble
Lukas M Payne, Wolfgang Langbein, Paola Borri
We report a simple, rapid, and quantitative wide-field technique to measure the optical extinction and scattering cross-section of single nanoparticles…
Polariton states bound to defects in GaAs/AlAs planar microcavities
Joanna M Zajac, Wolfgang Langbein, Maxime Hugues +1
We report on polariton states bound to defects in planar GaAs/AlAs microcavities grown by molecular beam epitaxy. The defect types relevant for the spatial polariton dynamics in th…
Realistic heterointerfaces model for excitonic states in growth-interrupted quantum wells
Vincenzo Savona, Wolfgang Langbein
We present a model for the disorder of the heterointerfaces in GaAs quantum wells including long-range components like monolayer island formation induced by the surface diffusion d…
