About the book
The aim of this book project is to cover a comprehensive and up-to-date collection of LEDs. This book will cover the recent advances in perovskite LEDs, organic LEDs, Quantum dot LEDs, nitride-based LEDs, etc. Organic LEDs are well known and already in the market and quantum dot-based LEDs are based on nanoparticles, and their structures are similar to the OLEDs. In 2014, the first perovskite LED was fabricated and after that, a lot of improvements have been done in this area. III-nitrides semiconductor materials including GaN, InN, AlN, and their alloys InGaN, AlGaN, etc. are promising semiconductors. The Nobel Prize in Physics 2014 was awarded jointly to Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura for the invention of proficient blue LEDs. After the invention of GaN-based blue LEDs, there was a revolutionary development in the III-nitrides-based semiconductor industry worldwide.
