The advent of III-nitride light-emitting diodes （LEDs） has revolutionized optoelectronics， driving significant advancements in theory and practice. This book， Characteristics and Applications of III-Nitride Light Emitting Diodes， comprehensively analyzes III-Nitride LEDs properties， challenges， and innovative potential.
In Chapter 1， we begin with the characteristics of lll-nitride LEDs， exploring quantum transport and theoretical models. Chapter 2 analyzes luminescence characteristics， discussing the impact of carrier distribution nonuniformity， valence subband coupling effects， and efficiency evaluation methods for different LED types. Chapter 3 delves into advanced design strategies to improve light emission， focusing on mitigating polarization effects and enhancing surface emission in deep-ultraviolet LEDs. In Chapter 4， we cover the optimization of surface structures to improve light extraction efficiency. Finally， Chapter 5 explores the influence of LED characteristics on visible light communication (VLC） performance， presenting techniques to alleviate nonlinearity impacts， optimize modulation characteristics， and improve overall system efficiency and reliability.
This book aims to provide researchers， engineers， and students with a deep understanding of III-nitride LEDs， integrating theoretical insights with practical design strategies. We are grateful to all contributors and reviewers whose expertise and dedication have made this comprehensive resource possible.
