Nanostructured Sensors
SPIE Professional - July 1, 2008
Infrared photon imaging between 3 and 14 μm has important applications in security, defense, astronomy, and a number of other areas. Researchers at the CQD have overcome several challenges in integrating Type II superlattice materials into IR imaging systems. Their innovative work using Nanotechnology to create these structures has resulted in fabrication of the first high-quality IR camera with a 10 μm cutoff wavelength. ... [read more]
