Low-light Photodetector Senses Shades from UV to NIR

Researchers at RMIT University (Australia) introduced a hyper-efficient broadband photodetector capable of imaging all shades of light between the UV and near-infrared ranges and is at least 1000× thinner than existing commercially available photodetection devices. The construction of the prototype featured a single nanothin layer on a chip, as opposed to a stacked structure of three or more layers. The technology improves biomedical imaging possibilities and capabilities, especially in the early detection of diseases and other health issues. Operating speed, low-level light sensitivity, and the extent to which they can sense the full spectrum are conventional gauges for the effectiveness and versatility of photodetection...
