Studying Hole Diffusion in InGaN Quantum Well Structures

Ternary nitride alloys, such as InGaN, are currently the materials of choice for light-emitting diodes (LEDs) operating in the visible and ultraviolet spectral range. Researchers from Vilniaus Universitetas / Vilnius University, UC Santa Barbara, and Centre National de la Recherche Scientifique applied the light-induced transient grating (LITG) technique to study the hole diffusion in InGaN quantum well (QW) structures, … Continue reading

Studying Ultrafast Relaxation Processes in Ag Nanocubes

Noble metal nanoparticles patterned in ordered arrays interact and generate plasmonic surface lattice resonances. Up to now, the assumption was that such nanoparticles are static. But researchers from the Kaunas University of Technology in Lithuania have demonstrated that this is not the case at ultrafast time scales. They used Transient Absorption Spectroscopy (TAS) to study … Continue reading
