Atomically Thin Cameras

What is it about?

Photodetectors have to be both sensitive to, and quick to respond to, small changes in illumination. We have demonstrated for the first time an atomically thin photodetector that can detect light under half-moon illumination levels, whilst operating at video-frame-rate imaging speeds.

Why is it important?

Unlike other atomically thin photodetectors, the high photo-sensitivity of our devices is achieved without compromising on operational speed. Our findings could enable the creation of atomically thin video cameras capable of night-time operation.
