Effect of Current on the Inhomogeneous Light Emission From AlGaInP-Based Flip-Chip Red Mini-LEDs

The distributions of the electroluminescence of AlGaInP-based flip-chip red light-emitting diodes with a size of $100\,\,\mu \text{m}\,\,\times 200\,\,\mu \text{m}$ have been obtained via microscopic hyperspectral imaging by capturing spatially resolved light emission from the side of a transparent substrate. As the injected ...
