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

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 ...
