ULTRAVIOLET DETECTORS: Nitrides push performance of UV photodiodes
ULTRAVIOLET DETECTORS: Nitrides push performance of UV photodiodes
Laser Focus World, p. 47-51 - September 1, 2009
Nitrides offer considerable advantages over other materials for ultraviolet detection. Recently, they proved useful for creating the world’s first UV single-photon detectors with efficiencies to 20%–detectors that could enable quantum computing and data encryption. ... [read more]

Superlattices see in the dark
Superlattices see in the dark
SPIE Newsroom - July 28, 2009
Six years ago, the Center for Quantum Devices (CQD) at Northwestern University fabricated the first IR camera based on Type-II material. After that, the CQD focused on improving the optical and electrical performance of the imager. We developed a new variant of a type-II superlattice, called M-structure, because of the M-shape of the band alignment, which allows for more-flexible control of the energy gap, energy levels, and effective mass. Many processing imporovements were also developed. The design, fabrication, and processes improvments have combined to make type-II superlattices a viable alternative to HgCdTe for IR imaging. ...

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. ...
