Wide bandgap semiconductors, made from such materials as GaN, SiC,
diamond and ZnSe, are undergoing a strong resurgence in recent
years, principally because of their direct bandgaps which give them
a huge advantage over the indirect gap SiC. As an example, more
than 10 million blue LEDs using this technology are sold each
month, and new, high-brightness (15 lumens per watt),
very-long-lifetime white LEDs are under development with the
potential to replace incandescent bulbs in many situations.
WIDE BANDGAP SEMICONDUCTORS provides readers with a broad
overview of this rapidly expanding technology, bringing them up to
speed on new discoveries and commercial applications. It provides
specific technical explanations of key processes such as laser
diodes, LEDs and very high temperature electronic controls on
engines, focusing on doping, etching, oxidation passivation, growth
techniques, and more...
The volume also explores the potential use of these
semiconductors in HDTV, power conditioning devices, and high power
microwave applications. The contributors are all experts in the
fields of growth, processing, and characterization of these
semiconductors, including II-VI compounds, processing techniques
for SiC, GaN and diamond, and materials analysis of all wide gap
semiconductors.
