Ammonothermal trumps HVPE
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.


LED droop discovery
Employing a non-polar design with an electron blocking layer to abolish carrier spillover and a gallium-doped ZnO p-contact to eliminate current crowding could be the key.


Low down on subtrates
Compound Semiconductor discusses the current and forthcoming issues for substrates with three leading industry figures.


Multiple applications beckon for UV LEDs
Brighter, more powerful and longer lasting UV LEDs promise to offer a viable alternative to UV lamps used to purify air and water, treat skin diseases, aid forensic investigations and combat forgery.


Laser productions to new planes
Defense, medical, instrumentation and display markets are all hankering after affordable blue and green lasers based on a single semiconductor chip.

Buoyant compound semiconductor market
According to AXT substrates sales will increase thanks to the combination of increasing GaAs content in mobile products, a resurgent LED industry and the beginnings of a terrestrial concentrating PV market.

Triple layer barriers to combat droop
Switching from a simple quantum barrier to multiplayer variant can boost internal quantum efficiency by cutting the polarization within an LED.
