Narrow band gap nanocrystals for infrared cost-effective optoelectronics

Infrared optoelectronics is driven by epitaxially grown semiconductors and the introduction of alternative materials often viewed with some suspicion until newcomer has demonstrated a high degree viability. nanocrystals have certainly reached this maturity switching from demonstration absorption chemists to their integration into increasingly complex systems. Here, we review recent developments relative nanocrystal devices in 1-5 µm range.
