Article Synopsis
- The study reports that etching the surface of GaN-based green LEDs with H3PO4 solution enhances their optical and electrical properties.
- By varying the etching time from 0 to 20 minutes, researchers were able to control the size and density of nano-sized etch pits, improving light extraction efficiency due to better photon escape angles.
- However, excessive etching beyond 5 minutes led to increased leakage current and degraded electrical performance due to larger etch pit densities.
