AXT benefits from a buoyant compound semiconductor market
Mar 04, 2010
Substrates sales will increase, argues AXT’s John Cerilli, thanks to the combination of increasing GaAs content in mobile products, a resurgent LED industry and the beginnings of a terrestrial concentrating photovoltaic market.
Kaai takes laser productions to new planes
Mar 04, 2010
Defense, medical, instrumentation and display markets are all hankering after affordable blue and green lasers based on a single semiconductor chip. Kaai aims to satisfy this demand with a portfolio of devices grown on semi-polar and non-polar planes. Richard Stevenson investigates.

The lowdown on substrates
Mar 03, 2010
Leading market analysts offer their take on the health of the GaAs, SiC, GaN and InP substrate markets, and predict how these sectors will evolve over the next few years. Richard Stevenson reports.
GaN 'important across a range of sectors'
Mar 03, 2010
Riber is set to provide new GaN products in the future.
Shedding light on the mystery of LED droop
Mar 02, 2010
Comparative studies have unveiled an LED architecture for realizing negligible droop: Employ a non-polar design with an electron blocking layer to abolish carrier spillover and a gallium-doped ZnO p-contact to eliminate current crowding, say a team of researchers from Virginia Commonwealth University and Kyma Technologies.
Bulk GaN: Ammonothermal trumps HVPE
Mar 01, 2010
Today’s GaN substrates are manufactured by a HVPE process that requires high temperatures and substantial reactor maintenance. Ammonothermal growth can address both these issues, while producing material with far fewer dislocations in a more efficient manner, says Ammono’s Robert Dwilinski, Roman Doradzinski and Marcin Zajac.
