Investigation of Electrical Properties and Reliability of GaN-Based Micro-LEDs

In this paper, we report high-performance Micro-LEDs on sapphire substrates, with pixel size scaling to 20 µm and an ultra-high current density of 9902 A/cm<sup>2</sup>. The forward voltages (V<sub>F</sub>) of the devices ranged from 2.32 V to 2.39 V under an injection curren...
