Light-Emitting Diodes: ZnO does away with green-LED problem
Light-Emitting Diodes: ZnO does away with green-LED problem
Laser Focus World - November 2, 2008
While blue and red LEDs can be made to shine brilliantly and have a long life, high-brightness green LEDs tend to die early. Now, scientists at Northwestern University (Evanston, IL) and Nanovation SARL (Orsay, France) have developed a type of green LED that has the potential to burn brightly while enduring year after year. Still in the early prototype stage, the hybrid-LED has a novel design that keeps the indium within its diode structure from diffusing over time and reducing the diode’s light output. ...

Powerful QCLs eye remote sensing
Powerful QCLs eye remote sensing
Compound Semiconductor - October 15, 2008
Our eyes tell us a great deal about our environment. However, they can’t spot the numerous invisible threats to our health and safety. What’s needed is a low-cost remote chemical sensor. Optical detection schemes are ideal for this task because they can quickly cover vast areas with high-power lasers that are directed far from the detection system. The most promising source for remote mid-infrared sensing is the quantum cascade laser (QCL), currently being developed by researchers at the Center for Quantum Devices. ... [read more]

ZnO/GaN hybrid shows green LED promise
Compound Semiconductor .Net - September 3, 2008
Hybrid LED structures featuring GaN and ZnO layers could produce higher performance green emitters than existing devices. Northwestern University and French startup Nanovation showed the concept's feasibility by making an LED with peak continuous-wave electroluminescent emission in the order of 2 mlm at 510 nm. These results were published in the in the August 25th issue of Applied Physics Letters. ... [read more]
