Recent discovery of neutral bremsstrahlung (NBrS) mechanism electroluminescence (EL) in noble gases two-phase detectors for dark matter searches has led to a prediction that NBrS EL should be present liquids as well. A rigorous theory was developed accordingly the framework Cohen-Leckner and Atrazhev formalism. It been recently followed by first experimental observation liquid argon, which howe...
We demonstrate CP-OLEDs with an impressive electroluminescence dissymmetry factor ( g EL ) > 0.3. The handedness of circularly polarized PL/EL can be inverted by varying the active layer thickness and chiral additive loading ratio.
Intersubband electroluminescence is reported in a quantum-cascade structure based on asymmetric superlattice active regions and designed for emission in the THz range ~l'80 mm!. Comparison with a structure based on a ‘‘vertical transition’’ in a single quantum well shows an increased full width at half maximum ~2.8 vs 0.9 meV! of the emission line. In both cases the dependence of the optical po...
