Abstract :
For decades, humankind has tried to harness the power of invisible light to image or communicate beyond what our eyes can see. Significant attention has been focused on near infrared (NIR) spectrum, and different types of infrared detection methods have been proposed and developed. Here, we report a new NIR detector based on a type-II band alignment and nano-scale sensing volumes.
