Researchers demonstrate long wavelength led based on InGaN on silicon technology
US research firm RoseStreet Labs (RSL) has made what it claims is the world's first demonstration of a long wavelength led device utilising low cost silicon wafer substrates.
The led was fabricated using commercial scale deposition tools at the company's Nitride Research Center in Phoenix, Arizona. The researchers believe it could offer significant advances in solid state lighting, led backlighting and next generation display technology.
"Green and longer wavelength leds have been sought after by both science and industry for an extensive period of time," said Bob Forcier, RSL ceo. "This device illustrates great promise due to its potential for high intensity, low energy consumption and low commercial cost. We are quite excited about the potential of this device"
RSL now plans to package the green and longer wavelength leds through its sister company, FlipChip International. Commercialisation is expected within the next two to three years, with migration to 200mm silicon substrates.
