Quantum Dot NIR Image Sensors

Near infrared sensing is getting very important in such devices as photo-cameras (for biometrics), autonomous cars (obstacles detection), machine vision (quality control and product inspection), AR and VR (for eyes tracking), in night vision and surveillance. Current active NIR absorbers, such as InGaAs and Ge, have high cost of production (high temperature epitaxial method) and cannot be integrated on a Si-based integrated read out circuit (ROIC). QDot™ PbS QDs have higher sensitivity, wider absorption range and compatibility with Si-based sensors.
