Quantum Physics and Technology with glamour – How diamonds make the quantum internet possible
Origin of the parasitic luminescence of 235 nm UVC LEDs grown on different AlN templates
/en/research/publications/origin-of-the-parasitic-luminescence-of-235-nm-uvc-leds-grown-on-different-aln-templates
AlN layers annealed at high temperatures offer low threading dislocation densities of mid 108 cm-2 and are therefore increasingly used as base layers in ultraviolet (UV) light emitting diode…
Improved far-UVC LEDs: investigations reveal causes of unwanted UVA radiation
/en/research/research-news/improved-far-uvc-leds-investigations-reveal-causes-of-unwanted-uva-radiation
High-resolution spatial measurements uncovered the origin of unwanted parasitic emission at long wavelengths from UVC LEDs. We are now able to implement targeted changes to the manufacturing process,…
