MAXIMIZING THE LIGHT EXTRACTION EFFICIENCY FOR ALGAN-BASED DUV-LEDS WITH TWO OPTIMALLY DESIGNED SURFACE STRUCTURES UNDER THE GUIDANCE OF PSO

Maximizing the Light Extraction Efficiency for AlGaN-Based DUV-LEDs with Two Optimally Designed Surface Structures under the Guidance of PSO

A novel method of utilizing an intelligent algorithm to guide the light extraction surface structure designing process for deep-ultraviolet light emitting diodes (DUV-LEDs) is proposed and investigated.Two kinds of surface structures based on the truncated pyramid array (TPA) and truncated cone array (TCA) are applied, which are expected to suppres
