Light Emission Induced by Charge Carrier Diffusion in Nanowires: from Synthesis to Characterization

Light-emitting diodes (LEDs) are widely applied in fields ranging from solid-state lighting and high-resolution displays to optical communication and sensing. Despite their remarkable technological development, conventional thin-film LEDs remain constrained by strain-induced defects from lattice mismatch and restricted light extraction efficiency due to total internal reflection. Exploration of alternative device geometries is motivated by these challenges.Semiconductor nanowires (nanowires) pro
