Nitride Semiconductor Light-Emitting Diodes (LEDs): Materials, Technologies, and Applications, Second Edition reviews the fabrication, performance and applications of the technology, encompassing the state-of-the-art material and device development, along with considerations regarding nitride-based LED design. This updated edition is based on the latest research and advances, including two new chapters on LEDs for large displays and laser lighting. Chapters cover molecular beam epitaxy (MBE) growth of nitride semiconductors, modern metalorganic chemical vapor deposition (MOCVD) techniques, the growth of nitride-based materials, and gallium nitride (GaN)-on-sapphire and GaN-on-silicon technologies for LEDs. Nanostructured, non-polar and semi-polar nitride-based LEDs, as well as phosphor-coated nitride LEDs, are also discussed.
The book also addresses the performance of nitride LEDs, including photonic crystal LEDs, surface plasmon enhanced LEDs, color tuneable LEDs, and LEDs based on quantum wells and quantum dots. Further chapters discuss the development of LED encapsulation technology and fundamental efficiency droop issues in gallium indium nitride (GaInN) LEDs.
It is a technical resource for academics, physicists, materials scientists, electrical engineers, and those working in the lighting, consumer electronics, automotive, aviation, and communications sectors.

Prof. JianJang Huang received the B.S. degree in Electrical Engineering (EE) and the M.S. degree in Graduate Institute of Photonics and Optoelectronics (GIPO) from National Taiwan University (NTU), Taipei, Taiwan, in 1994 and 1996, respectively, and the Ph.D. degree in Electrical Engineering from the University of Illinois, Urbana-Champaign, in 2002. He had worked with WJ (Watkins Johnson) Communications in California, as a Staff Scientist from 2002 to 2004. He then came back to Taiwan in 2004 and is currently the professor at NTU EE and GIPO.
Prof. Huang has been involved in the development of optoelectronic and electronic devices. He has developed a spin-coating method for nanosphere lithography (NSL) to significantly improve the performance of light emitting diodes (LEDs), solar cells and nanorod devices. His NSL approach has been licensed to several LED companies in Taiwan. He has also fabricated and characterized IGZO TFTs and the corresponding circuits on glass and flexible substrates. In recent years, his group has spent great efforts in realizing cancer cell probes using ZnO nanorods, and high-sensitivity protein sensors based on IGZO TFTs.
Prof. Huang is a member of the Phi Tau Phi Scholastic Honor Society. He received "Wu Da-Yu award in 2008, the most prestigious one for young researchers in Taiwan sponsored by National Science Council. And in the same year, he received the award for the most excellent young electrical engineer from the Chinese Institute of Electrical Engineering. He has served in several IPO committees in Taiwan Stock Exchange. He is currently the board director of GCS holdings in Torrance, CA, USA and the conference chair of SPIE, International Conference on Solid-State Lighting.
Professor H. C. Kuo received the B.S. degree in Physics from National Taiwan University, Taiwan the M.S. degree in Electrical and computer engineering from Rutgers University in 1995, and the Ph.D. from Center of Compound Semiconductor Microelectronics (CCSM) of University of Illinois- Urbana Champaign in 1998. He has an extensive professional career both in research and industrial research institutions that includes: Research Consultant in Lucent Technologies, Bell Lab (1995-97); Member of Technical Staff in Fiber-optics Division at Agilent Technologies, USA (1999-2001) and Manager of LuxNet Corporation, USA (2001-2002).
