Green and Longer Wavelengths by InGaN-on-silicon LED

The world's first long-wavelength LED devices using low-cost silicon wafer substrates were demonstrated by RoseStreet Labs. The company says its technology will find a home in the rapidly growing global LED lighting market where energy efficiency, low cost, and miniaturization are critical product characteristics. The technology, which enables green and longer-wavelength LEDs out to 575 nm, is a significant milestone considering that such longer-wavelength nitride-based LEDs have, until now, been challenging to fabricate compared to blue and ultraviolet (UV) LEDs d...

RoseStreet Labs Develops World's First Silicon-based Long Wavelength LED Device

RoseStreet Labs, (RSL), has utilized low cost silicon wafer substrates to develop  the world's first long wavelength LED device. The RSL longer wavelength device is fabricated utilizing commercial scale deposition tools at RSL's Nitride Research Center in Phoenix, Arizona. In contrast to the more traditional sapphire or silicon carbide substrates typically utilized in LED fabrication, silicon substrates have a substantial cost advantage. Green or longer wavelength nitride based LEDs are very challenging to fabricate compared to UV and Blue ...
