Taking a picture with a single photoresistor is a brain-breaking idea. But go deeper and imagine taking that same picture with the same photoresistor, but without even facing the object. [Jon Bumst… ...

We have demonstrated for the first time that under suitable gate biases, single CdS nanobelt (NB) metal-semiconductor field-effect transistors (MESFETs) can serve as high-performance photodetectors.
