Ground State Electroluminescence [PDF]

Physical Review Letters, 2016
Electroluminescence, the emission of light in the presence of an electric current, provides information on the allowed electronic transitions of a given system. It is commonly used to investigate the physics of strongly-coupled light-matter systems, whose eigenfrequencies are split by the strong coupling with the photonic field of a cavity.

Deep-ultraviolet electroluminescence and photocurrent generation in graphene/hBN/graphene heterostructures [PDF]

Nature Communications, 2021
Hexagonal boron nitride (hBN) is a van der Waals semiconductor with a wide bandgap of ~ 5.96 eV. Despite the indirect bandgap characteristics of hBN, charge carriers excited by high energy electrons or photons efficiently emit luminescence at deep ...

Thermal assisted up-conversion electroluminescence in quantum dot light emitting diodes

Nature Communications, 2022
Up-conversion electroluminescence, in which the energy of a emitted photon is higher than that of the excitation electron, is observed in quantum-dot light-emitting diodes. Here, we study its mechanism by investigating the effect of thermal energy on the

Deciphering exciton-generation processes in quantum-dot electroluminescence [PDF]

Nature Communications, 2020
Electroluminescence of colloidal nanocrystals promises a new generation of high-performance and solution-processable light-emitting diodes. The operation of nanocrystal-based light-emitting diodes relies on the radiative recombination of electrically ...

Automatic Classification of Defective Photovoltaic Module Cells in Electroluminescence Images [PDF]

Solar Energy, 2018
Electroluminescence (EL) imaging is a useful modality for the inspection of photovoltaic (PV) modules. EL images provide high spatial resolution, which makes it possible to detect even finest defects on the surface of PV modules. However, the analysis of
